1 – HP 35s Scientific Calculator
Top Reviews I have now been forced to buy 3 of these things (HP35s). It is hard to find RPN HP calculators any more for any reasonable price, so this is why I continue to buy it. But I am getting tired of the product quality. The first one died after 2 years and 1 month (one month past the HP warranty). Pressing the keys just resulted in garbage on the screen, Replacing the batteries (themselves a high cost) and going through troubleshooting did nothing to fix it. Bought it again after this, and the package arrived broken or cut open and some of the keys did not function at all. Returned this one within 30 days (prompt refund, without questions) and bought yet another. If this one dies an early death, I will be done with this HP model and maybe HP altogether. I have used HP RPN calculators since the first ones over 45 years ago. The early ones lasted forever, and the new ones barely function; in addition, they key layout is much more awkward and cumbersome.UPDATE: I got my new 35s today. Took it out of the container (this time it was not busted open). Put in the new batteries. And lo-and-behold. Nothing. NONE OF THE KEYS work at all. This thing is the biggest piece of trash I have ever seen. Amazon – you say this is your “preferred choice”?? What is this rubbish? How can it be that I get three of these in a row, each one worse than the last? Either HP has gone completely downhill or Amazon is allowing its vendors to sell pirated calclulators. I’ll return this AGAIN. I am really sick and tired of driving to the post office to return garbage being sent to me. . The caveat is that I am not steeped in the HP calculator tradition and only used their RPN calculators sparingly. Others — particularly scientists and engineers — may have legitimate complaints about this unit.Upon retirement as a software developer, I am able to indulge in my amateur radio hobby more and, perforce, need a decent scientific calculator. This unit seemed to be a good choice and, as I progress, RPN seems like one of those I could have had a V-8 phenomena. I am sorry I did not do this earlier. That said, methinks many doth protest too much and need to get a life. If one is disappointed because it’s not an HP-41, then one should explore eBay and pick from the many older units that abound — for three or more times the HP 35s (approx.) $55 MSRP.The calculator is solidly built and has a nice tactile response and is loaded with features. It sits nicely on the desk and the display is at the proper reading angle. It has solid rubber feet which stop it from sliding all over the surface. Thus far — with an intense learning curve for me to overcome — I have not noticed key bounce or missed keystrokes. But if people say they have experienced that, I will be alert for same. But, all in all, it is a nice instrument.Of course, there are downsides.(1) One cannot upload or clone programs from other sources; I presume this is to allow these to be used in various engineering exams, etc. But programming can be done manually and there is a decent section in the user’s guide on that. Interestingly, HP 35s calculators that have been pre-programmed can be had on Amazon and eBay for something on the order of $225. It tickles the imagination just how they got these programmed unless, of course, they employed a phalanx of engineering students to laboriously hand enter the formulas.(2) The different bases (binary, octal, decimal, hexadecimal) are somewhat cumbersome to use. But — and I do not wish to be glib here — I did not buy the calculator for that reason. The internet abounds with FREE Windows and MAC and Android scientific calculators that handle number bases in a more logical fashion. Reviewers have pointed out how other keystroke sequences are cumbersome but being a scientific and mathematical ignoramus, I have not noticed anything yet.(3) The user’s manual is on an accompanying CD. For a short time, HP shipped the unit with a printed paperback NOT the nifty, handsome, spiral-bound manuals they used to produce. But, several years ago, they went all Greenpeace/tree-hugger on us and dumped it to CD. DESPITE WHAT THE MANUAL SAYS, HP DOES NOT HAVE A PRINTED VERSION ON REQUEST FROM CUSTOMER SUPPORT. Also note that there are multiple language versions of the manual thereon the CD. To this point, I have several calculators who sent along those little paperbacks that I found inconvenient to make notes in or otherwise paw through. Also, the have gotten lost.uh.somewhere in a move over the past 25 years or so. Since I am in a catching-up learning curve, I am printing mine chapter by chapter and working through each chapter as I go. (By the way, I recommend you print it two-up as it is 380 pages long.(4) While this is not a downside, a lot of folks have gone off on the new case that ships with the HP 35s now. It is a departure from the original zipper case that harkens back to the older HP models. I find the newer slip case to be sturdy and durable and works just fine and NOT to be a reason to avoid purchasing a 35s. In fact, it is more convenient to stow and remove the unit from this than the earlier version. However, the older case did allow for storage of notes and other items in addition to protecting the calculator. It is easy to see why surveyors or others in the field would favor that.Will get back later with any other regrets as conditions warrant. . The HP35s may not be perfect but it’s close and only the most finicky users will get too worked up about its deficiencies. There’s a list of two dozen bugs over at hpcalc.org, but none of them are show-stoppers as far as I’m concerned. It would be great if the firmware could be updated, but that’s technically impossible, so we’re locked into “it is what it is”, bugs and all, forever.From what I can collect by reading the forums the most egregious bug is a failure to round properly in the 13th decimal place. So, for example, 0.0123456789012 + 0.000000000000051 = 0.0123456789013 as it should, but 0.0123456789012 + 0.000000000000050 = 0.0123456789012 which is technically wrong. This gets reported as “TAN doesn’t work”, which seems like an exaggeration, imho. Like I said, not a show-stopper for me. The other really big problem is that it’s possible to put the calculator into an infinite loop that locks the device, requiring a hard reset and clearing all memory. If you’ve spent a lot of time entering custom programs by hand, with no way to transfer them to or from a computer, clearing all memory is a really big deal. But face it, you can download Free42, for, um, free, and run it on any old handheld device. It can import/export programs, and is a perfect clone of the renowned HP42S. If you can’t afford to lose your programs then something like that is your better solution anyway, or an upgrade to the HP Prime with its computer interface.Now for the good news! Playing with this I’ve been on a nostalgia high for the past 48 hours. Much more so than the HP50g, which never delivered quite the same kick – too advanced, or too big, or too something. The HP35s, on the other hand, is really similar to my old HP22S in size and feel, while being far more powerful and having RPN. It just “satisfies.” The keys are responsive, the form-factor is comfortable and convenient, and the appearance is gorgeous, far superior to the toy like calculators HP made and still makes for the education market. For all these reasons it’s a sweet collectible, in addition to being useful.The HP50g was released in 2006 and discontinued in 2015. Considering that the HP35s was released in 2007 it feels like it’s living on borrowed time. If, like me, you’ve always sort of wanted an HP35s you may want to pull the trigger now while it’s still readily available.One complaint: on page 42/43 of the “Quick Start Guide” that comes with the calculator, it says, ” in addition to this quick start guide, a printed copy of the users’s guide can be obtained free of charge by calling HP Customer Care at 800-HP-INVENT.” I’ve read online that people did succeed in doing that, but when I
called HP this morning I was told that there are no more manuals available; they were all sent out and no more are being printed. So, if you want a printed manual, you’ll have to print and bind yourself the 382 page PDF that comes on the enclosed CDROM, despite what the lying Quick Start Guide says. To be honest, I didn’t really expect HP would honor that promise – it just would have been nice not to have to spend fifteen minutes on the phone to find out.p.s. there’s a movement afoot to reverse-engineer and re-release some of the classic HP calculators. Check out the , an HP-15C clone. . Having used RPN calculators since I bought my first Hewlett Packhard (32SII) one as a student, I am never very confident with ‘normal’ calculators. My original calculator still works fine despite being heavily used over 40 years(!) and being dropped many times, but I decided I wanted a second one so I could leave one at work and one at home. Not surprisingly, HP don’t make the same model any more so I bought this one which looks like it is the nearest equivalent. It works OK but I prefer the earlier model which was much thinner and had less info on the screen at one time. After buying this I managed to get a second hand 32SII version on ebay. Read more
2 – Saunders Blue SlimMate Plastic Storage Clipboard�� Light Weight,�Polypropylene�Clipboard�for Students, Teachers, Parents, Sales, Utility, Industrial, Office Professionals.�Stationery Items
Top Reviews The major design flaw on this is that the clip used to hold the storage compartment closed has a tendency to fall off when you have the storage compartment open. I just got the item and it is already doing this. It will get worse over time. I managed to partially fix the problem by taping it on with a piece of electrical tape. This is only a partial fix as it will still fall off, just you won’t lose it this way.The other flaw is the plastic is not really that hard. It does flex and bend quite a bit when you write on it. It doesn’t annoy me too much but it can annoy some people. I’m dealing with visual impairment since last year so I write pretty big with marker pens anyways, so it won’t be a huge issue for me. If you are writing small, I think it can screw you up. If you fully stuff the inside compartment with paper, you might not have as much issue as it will keep the plastic from bending downwards as much, but that will add weight to your set up.Another complaint is the area for storing a pen is only enough for 1 pen or pencil. If you want to store a backup, you have to use the paper storage section, it will roll around and make noise unless you have the whole compartment stuffed with paper.Overall, I would have probably given this product a 1 or 2 star rating, but the manufacturer claims to be using employees that are blind and disabled to assemble these in the US. I’m giving them 3 stars for that as I support helping the disabled get employment, especially for the blind community. The design flaws can not be overlooked though therefore I will not be giving a 5 star review. . Surprised at the quality of this clipboard.Please watch the video for more info. I bought this to organize my 3.5 year-old son’s pre-k papers. It has held up great to his care.I am super impressed by the quality and the amount of storage it provides. I would definitely recommend this product. . I work for FedEx. This is great for keeping forms, supplies, and extra pens handy while also working as a clipboard. I’ve been using it for about 5 months as of the writing of this review, so I can attest to it’s durability. Both the top clamp and the locking clip are well constricted and easy to operate. I’d buy another one in a heartbeat, but it looks like I won’t have to for a while.12/01/11: Coming up on a year and this clipboard is still in great condition. Yeah, it’s got a few scuffs on the back, but the hinge, top clamp, and the locking clip are still as good as they were on day one!08/20/16: I’ve had this clipboard 6 years now and it still works as great as it did the day I bought it. It doesn’t get heavy use. I carry it from my locker to the truck and back again in when finished. I open it whenever I need it’s stored goodies (maps, labels, band aids), and use the clip for a few forms. Still going strong! . This storage clip board works as intended for my purposes.Although lightweight, it feels sturdy. There is ample storage inside for some paper and pens.A regular plastic stick pen will slide into the external clip for easy access storage as well.The the tension on the clip is set well, being strong enough to hold the paper in place, but not so strong as to be difficult to lift when inserting or removing sheets of paper.I also like being able to use a stick pen or CD case to prop open the lid to use this clip board as a lap desk or to hold copy up at an angle so that it is easy to read when typing on a keyboard.
