The keys don't respond well, thus when you hit the button for the answer you are looking for, you wonder why it is off or simply wrong,,, because the keys don't respond well. This calculator is a piece of junk.
Major Calculation Bug April 20, 2002
13 out of 18 found this review helpful
I found out that the calculator produces wrong Interest Rate Payment calculation results. There must be a bug in the calculator's formula chip. The calculated results wouldn't even match the ones in the manual that came with the calculator.
I would stir clear of this model and go for a different model.
 HP 10B Calculator not up to standards August 30, 2002

Having used HP business calculators for nearly 20 years, and having taught over 30,000 people how to use them, I am very disappointed in the HP10BII. It appears to me that HP built a calculator to compete with the "cheap" business calculators on the market. They succeded in building a "cheap" calculator. If it were merely inexpensive, it would be fine, but it's "cheap". I have never had an HP calculator go bad until I had a 10BII. Less than a year after buying it, half of the display disappeared. After changing batteries - never required in the first year of ownership of any other HP business calculator, the display came back for a day. HP graciously replaced it with a calculator that had a key go bad within two weeks. A third calculator is on the way. HP used to have a reputation of having the most durable and dependable calculators on the market. They have lost that reputation with this piece of junk. I don't know if I will ever again assume that an HP calculator is a good calculator. The only reason I still use it is because the 10B is no longer available and the College for which I teach wants students to use the 10BII.
Junk, just junk May 23, 2002

For quite a while I used the HP 10B which was a fine machine -and then I misplaced it. I bought the 10B-II to replace it and found that it is really not at all the same machine. There are at least two ways in which the 10B-II is so bad as to be properly described as junk.First, the movement of the keys is very poor... If you don't press a key with just the right pressure it will either not register or will register twice. This makes the calculator very hard to use because you have to go very slowly or you will make an error (and not know that you did). Second, the positions of some of the keys have been moved; it is now very easy to erase all the memories accidentially. The "clear entry" and the "clear all memories" are the same button and if one happens to touch the shift key first all the stored information will be erased! If you spend some time doing a project (or filling out your tax return) you probably will accidentally erase all the numbers you have stored and find it necessary to begin again. I may add that the 10B-II shares one error with its fine predecessor: If you perform a regression the machine will calculate predicted values of x as well as y using the same equation. This is mathematically incorrect, and the people who designed this machine should have known better. After some months I happened to locate my misplaced 10B and the above comments are based on a side-by-side comparison of the two. The 10B is very nice -smooth movement of the keys which makes it very easy to use and accurate. If you happen to see a 10B buy it -but avoid the 10b-II -it is unworthy of the Hewlett-Packard name.

I bought this caluclator about one year ago. At first it worked nicely. A few days ago I went to use it and the screen was not working correcly. Characters would not show up and basically it became instantly useless.
I would not recommend this product or buy another HP calculator. For a calculator not to work correctly in such a short period of time is in my opinion poor quality and HP's disregard for quality.
By the way, this calculator was never abused in any way. It sat in a desk with the cover on. Definitely look elsewhere.
