Why HP15c CE "Enhanced" ?

We are offering theHP15c CE "Enhanced" at a 10€ premium over the standard price of the HP15c CE.

What makes it "enhanced"? 4 main items, in my opinion.

• We implement the latest firmware with a correction for the HP16c hidden mode, so that it is not affected by the DEC bug.
• We include a HP16c overlay so you can use the HP16c mode with ease.
• We include a programming cable so that you can change the firmware when new versions appear with more functions or solutions for yet unknown bugs. (In particular we are working on a back up feature - memory is big enough to save it just in case. Alternatively, you can have several profiles (finance, electrical, construction, algebra) that can be changed with the back up feature)
• My preferred: a proper QC done by me. I open the calculator, see whether the bezel has any spot, and test the keyboard. In particular, I test all keys for recording properly using the self test feature, for any hard key (is fair to say that this test does not test for rebounds, but our new firmware also changes debouncing to 100ms from 80ms in the original machine)
