My New Hp10Bii is CRAP!!!!


What a piece of crap!!!

I bought one to upgrade my business collection. Right out of the blister pack it has a poor FV key (no key click at all, feels flat). All the other keys do have a keyclick, but not nearly as nice as the older line. This is new, out of an undamaged blister pack. A $10 calculator can be excused for this type of behavior, but a $30 retail calculator (with the Hp emblem no less)???

If I hadn't bought it at discount and had to rely on this to get me through a class, I would take it back and probably exchange it for a Ti. If the new Hp 12c's are like this and retail for $70, that is a crime!

I could buy a $20 Ti and have a much better made calculator than the overpriced Hp GARBAGE. When I use an (older) Hp, I know I am using the BEST. New users, will think Hp is CRAP, if they try out Hp's new offerings. What a great marketing concept. Any Hp Calculator development people reading this???

Perhaps this is why Hp is having outside companies relable their lines with the Hp logo.

Any arguements???

I am open to any.


My own personal HP-10BII had the FV key problem. That's interesting...seems like a sure fire design problem to show up on 2 new 10BII's.

The rear battery door ALSO does not stay clicked shut. I have to use scotch tape.

Needless to say, it's in a file drawer at home somewhere.

Compare the 10BII to the BAII Plus - same price range. BAII Plus wins hands down. There IS no comparison.

BAII Plus:
1) Uses worksheets to store statistical and cash flow data...each data point is accessible for correction. No such capability on the 10B or 10BII (or the 12c for that matter).
2) Has trig functions built-in.
3) Has HYPERBOLIC trig functions built in.
4) Has permutations and combinations built in.
5) Has the ability to make 1+2x3 = 7, like it should, without having to use parentheses! (When will manufacturers stop thinking business people are stupid?)
6) Has lots of other functions built-in too.

Same price? No decision needed. Buy the TI.

I hope that HP does better with a new high-end financial calculator.

Darn! I hope HP reissues the 12c in the form of a 12c+ with some of the changes I suggested last year.



I went through several replacements.. All Hp-10Bii's have the same failure in the FV key. Several had displays go bad on me also.



my 10BII (batch# CN03102032) doesn't have that failure.
The FV key works like the other keys.
Maybe another batch works better?

However, I must admit that this calc is crap.
I posted something on this matter last year,
keyword 'hamster shit' ;-)



I have a theory about the 'FV' key feeling consistently mushy on the 10BII, but to see what I mean, you might need to dismantle yours (which invalidates your warranty, etc., and might leave you with a non-functioning machine, for which I take no responsibility -- if you're not comfortable dismantling calculators, don't do this).

First, take the machine apart; it's just held together by three clips down each side, two at the top and one at the bottom -- insert a thin blade between the case halves and twist repeatedly, and you'll be able to pop the case open.

Note that there are four heat stakes around the battery contacts on the main board; these hold it in place against the front half of the unit. Note also that the keyboard frame is attached to the main board by two further smaller heat stakes, one at the top left of the main board, and one at the bottom right. If looking at the keyboard from the front (printed) side, the lower one is about at the
intersection of the 'C', '1', 'ON' and '0' keys, and the other is right below the right-hand hinge of the 'FV' key.

You can get a better idea of all this by cutting the heads off the heat stakes, and really dismantling the calc; if you don't do this, you'll be able to reassemble the calculator as if it had never been opened, but cutting the heat stakes can't be undone, and will leave you with a slightly looser machine upon reassembly. Anyway...

My theory, alluded to earlier, is that the stake right below the 'FV' key is having a bad mechanical effect on the key, either distorting the plastic frame around it, or pushing one side of it too close to the plastic dome underneath, or something similar which affects its ability to interact properly with the dome and the contacts underneath it. I don't think it helps that there are only two diagonally opposed heat stakes on the keyboard instead of the four that seem to have been planned for (there are four holes in the main board that look like keyboard stake holes).

If there's a mechanical engineer in the house who could comment on this one way or the other, I'd be interested in their opinion, especially as regards how predictable this problem would have been from the design, prior to manufacture.


I too have a 10BII which I am not happy with.

Your analysis of the construction is interesting and it would be good to have some photos of the insides to show us. Any chance of publishing some?


Do these help?

BTW, I was slightly mistaken/misleading in my earlier post with respect to opening the case. The four big heat stakes visible in the battery compartment hold the back on. However, I found that you could ignore them, and just pull the case halves apart anyway, with minimal (but noticeable) damage to the stakes themselves.


Thanks, that is a very comprehensive and illuminating answer!

I am not a mechanical engineer, but it seems obvious to me that the construction and materials are paired down so far for cost reduction that it is sure to cause low quality feel and operation.


Yet another problem I've had with my 10BII is that if I press lightly on the number keys (just enough to cause it to click), it sometimes fails to recognize the key press. This is a major problem with number entry if you aren't vigilantly examining every key press.

I really do like the overall looks of the 10BII, and the clarity of the display. Its too bad HP is now producing such awful quality products...


You left out: Can get the TI at any Walmart and most office supply stores. Walmart seems to be dropping the standard TI-BA model, but keeping the BA-II. The only picky complaints I have with the TI is no EE key so one must use a work around upon exponent entry as it has the capability, just not direct entry. Course in that role it could be a scientific/financial, that one quirk and either base 10 or E logs/exponential missing also, one or the other can't remember which being another preventing it from same without conversion.
I have not had problems with the 10BII in very limited use, have some new ones I got marked down in Walmart I now need to test through the plastic, however! I thought the keyforce was rather too high given the (lack of) case stiffness, though, which could explain some of the issues over time.


The BAII Plus is missing the BASE 10 logs.

And, the EE scientific notation is missing.

Still, for $30, this is a great business calculator with a lot of scientific stuff thrown in.

Sad to hear about the apparently normal 10BII FV key defects. I didn't bother trying to get a replacement. Just threw it in the drawer and gave up on the 10B.



$40/unit is quite expensive for a such poor quality calc.
I've got two HP-10B, more closed to HP standard quality built, and happy with those.

The HP-10BII is a very sorry piece of work. IMHO though !


I purchased my 15 year old son an HP30S. Scientific, with all sorts of "kewl" functions. (I wanted the kid to learn what the best was like, similar to the awe that I felt as a freshly scrubbed engineer learning how the "big boys" did it.)

Replaceable faceplates with different colours? Rubber keys? An equals sign? (But it was an HP. - Even if it did cost 80 bux Cdn)

At first he was thrilled, and his classmates even borrowed it. After five months, the equals sign (how apropos!) has quit working, the digit 8 no longer does it, and the calc lives the remainder of its non-working life in the bottom of the dreaded junk drawer. Now he is saving his money for a TI for high school - with my blessing.

I tried HP, but you let me down...


How sad your story is.

The Hp30s listed for $20 US.
It is not an Hp calculator of the same quality as an Hp20s (which lists for $40 US and is probably the calculator you paid for, but you got the Hp30s via the old switcharoo, either by plan or inept pricing).

That said, I suspect you will never again trust Hp calculators. GREAT MARKETING HP!!!

I would bet that you will badmouth Hp for a very long time ie years->forever.

To Hp:
No need to invest in marketing across the border, your manufacturing has spoken LOUD & CLEAR to Jim.
