Digital camera reviews of HP 33S Scientific Calculator (F2216A)
Digital camera Review: Affordable Rervese Polish
Summary: 5 Stars
I've been using the Reverse polish logic calculators for 25 years and everytime one "dies" I panic because they usually cost over $200. This one is just GREAT! Inexpensive and has all the features, whistles and bells any scientist could ask for! Highly recommendedDigital camera Review: Almost Unusable
Summary: 1 Stars
This is a great calculator except one major flaw (especially if you like RPN..and who doesn"t!!!!). Yes, there are a few things that peolpe are complaining about, most of which in my opinion are a matter of personal preference. However, one complaint that I have seen several times and that I agree with 100% is the 1-pixel decimal point! This is the biggest bone-head design error that I have seen in a long time. What were the designers thinking! If something like 6.6 is displayed, it's marginally OK. If 2.2 is displayed, the decimal point is virtually un-readable. The decimal point is a pretty important character to be so small that you have to scan the display to see if one may be hidden somewhere. The decimal should take an entire character space like every other calculator in the world. (I tried the "comma-for-decimal-point mode", but to no avail).All of the other great features of this calculator are dwarfed by this major flaw. I would wait until this was fixed before purchasing (too late for me).
I have contacted HP about this, and am waiting for a reply.
Digital camera Review: An Excellent Buy
Summary: 5 Stars
This is a great product for the casual user as well as the math freak. I've had mine for over a year now. I have used HP calculators since the mid-70's and most have been served me well.HP 33S Scientific Calculator (F2216A)Digital camera Review: At least it has RPN
Summary: 3 Stars
I have one 42s left (having left one on an airplane), and a 32sII in reserve, but since I will need to use RPN for the rest of my life, I bought a 33s.
It is too big, in the case, for your shirt pocket. Well, my 42s lives there anyway, but the 33s will fit without case in the shirt pocket. I am so slobby that while I wear a shirt and tie, I rarely wear a jacket. So, where do you stash the 33s?
But, please, can't HP come out with the 42s again? I managed to buy the 42s at $100 in 1990 when my 15c died. At the time I was a grad student in engineering living on a meager stipend provided by GM.
Now I make 20 times that amount. I might not pay $2000 for a good calculator, but I might.
The calculator does look better in real life than in the pictures, so it is not embarrassing. The decimal is too small, but not the end of the world.
Digital camera Review: Barely lasted a year. Recommend against.
Summary: 1 Stars
I used a 32sII at work for over 12 years. It was used when I got the position. It never gave me any trouble until the very end.
The 33s, on the other hand, gave trouble from the start.
I have to agree that the single pixel decimal and comma are almost impossible to see, especially at an angle. There's no way to adjust the "darkness" of the numbers like on the 32sII.
The small enter key is bad design.
But what's worse, almost immediately it started falling apart. One of the rubber feet fell off within a week.
The decimal key went "wobbly," and started being hard to use. Then the enter key, then the two, then the five. By "hard to use" I mean you have to keep an eye on the display ALL the time, because sometimes when you click a key, it doesn't accept the input. It FEELS like you've clicked, but nothing happens.
This is bad when you spend your day using a calculator. I've made do though, until now.
About two weeks ago it just stopped accepting any input. I shook it a bit, pushed random buttons, and eventually got it running again.. Then I did the self-test and the manual self test, which it passed both perfectly.
Now it's "died" again. Doesn't accept input.
I'm going to HAVE to get another one, but I cannot recommend this to anyone who can use a non-RPN calculator.
