1 – HP 10s Scientific Calculator (F2214AA#AK6)
Top Reviews
Haven’t had this calculator long enough to give a proper review. But so far so good. I prefer a white to a black background. Easier to see the extra functions above the buttons. On the display, it has dot matrix on top line and solid on bottom line. The solid line is easier to see. But dot matrix seems to be what most calculators are using. All of the four line calculators that I’m aware of use dot matrix. As well as most two line. The buttons work fine. It has sufficient functions (240) for most things. The only thing missing to my mind are the conversion factors. Perhaps I haven’t discovered it yet. Nevertheless, like all modern calculators, compared to what one can put on one’s computer, it’s just a toy. Or at most a scratch pad.Personally, I’m retired. When I was in school, we used a slide rule. Never found any reason to use anything else. So now that I’m retired, I’ve bought several electronic calculators just to see what they’re about. Easier to use I suppose. But the good old slide rule is better if one knows how to use it. Familiarity is the key, just like any tool. And like any tool, the slide rule and the electronic calculator each has certain advantages over the other. One thing the electronic calculator has over the slide rule, especially for the kids today, is that one doesn’t really have to think much to use one. It’s all done for you. Don’t have to remember anything, like how many zeros after the number or where the decimal point goes. Only need to remember how and where to put in what you want to calculate. They say that the electronic calculator is more accurate than the slide rule. Again, it all depends on how you use them. Prior to the era of the electronic calculator, bridges, buildings and rocket ships were built with total functionality (some still functioning) using the slide rule. It is my opinion that the only reason that the electronic calculator replaced the slide rule in popularity is because it’s human nature to think as little as possible. And as I said, one doesn’t really have to think much using an electronic calculator.Out of all the electronic calculators I’ve purchased so far, only one has a serious physical problem. Pressing on the battery lid, which is inevitable on this calculator because it’s right where one holds it, turns off the calculator. Not sure what the problem is. A short of some sort no doubt. But even that one is servicable if one remembers the problem. Familiarity.I have another problem with another type of calculator. Small print. But I will mention it in relation to that calculator. Has nothing to do with this one. The print on this calculator is large enough to be quite readable. And I do prefer the two line to the one line calculators. Don’t have to remember what I put in. It’s right there. My version mental laziness, I suppose.I am concerned that HP Prime is going to have small print. If so, I probably won’t bother with it when it comes out. Already have a couple with small print. I don’t see so good any more and they’re not color. I can still see a slide rule better than these small print calculators. Whether color would help that matter, I don’t know. Perhaps it might.But this one works fine and is sufficient for most things. Inexpensive to boot. Something for the kids to consider. They can always buy a more expensive one later if they need to. .
Display is scarcely readable. Maybe the battery is dead on arrival Nothing in the manual shows how to remove the cover to get to the battery, or what kind of battery to get. Tomorrow I will work on that but I bought this in order to take a school test. This is a slight delay for my test taking. I will have to either buy another calculator or fix the battery in this one and hope that solves the weak display. .
This calculator’s numbers hardly show up on the screen. I thought maybe using it in bright light due to the solar feature would help, but didn’t at all. Ended up going to Office Depot and getting a Texas Instruments. Like night and day. .
Another reviewer slammed this because it does not have the look and feel of the traditional HP calculator. Forget about him. This is a great inexpensive calculator. HP quality is not what it used to be anyway. I have one old HP-15C calculator that works beautifully and is 30 years old. Then I bought an HP financial calculator for $35 (an HP-10bII) and it broke after 1 year. Think of this HP-10s as a Japanese calculator with an HP label. It’s fine, but not really a Hewlett Packard.Since I first reviewed this calculator, I’ve purchased a 2nd. The display is failing on the first calculator. The 1 in the first position no longer displays. So this calculator has a lot of capability, but it is made with a poor quality display. I’ve reduced the rating from 5 stars to 4. It’s still good because it’s cheap, but don’t expect it to last. .
