Yes, this condition is unacceptable. I normally press keys consistently with just the force necessary to depress them, and the '6' key is a pretty important key. To use the calculator in this state, one must watch the display carefully to ensure that each keypress of the affected keys has registered. Very inconvenient, and unacceptable. I bought a used HP-41C advertised as 'works perfectly' a few years ago on TAS with this same problem (most likely developed over time with much use) and returned it for a refund.
I called buy.com this morning and found that they are completely sold out of HP-15C LEs, and will not be getting anymore. They informed me that they would be happy to take the return and refund my purchase. But I will not accept that offer as I want to end up with a unit, and it appears likely these are close to selling out. I wonder if HP will have any for sale on their own web site. I certainly hope that they have enough replacements for defective units that they must warranty.
