I just prefer using actual calculators, to using a smartphone. I got two with programming leads, I may set one in permanent 16C mode. I'm not going to nitpick over the keys, the label on the back and the binding on the manual. To have them made exactly like the original, would be too expensive and I doubt very much if anyone would be willing to pay the extra costs, even though I probably would. I'm lucky to be able to get one at all as the original ones are too old and not worth the money. My two units have consecutive odd serial numbers ending in 11 and 13.
Good morning. You remind me of my grandson playing and comparing his toys, a true perfectionist, trying to find any imperfections he may have. Sensational
That's an interesting and helpful exploration of the key bouncing. I've had mine a few months now and yes it does happen, but only when being rather slapdash with the keying. For any carefully entered calculation, I find it's a great tactile keyboard and for me, it's a lot more reliable for entry than a spongey Casio. Also, I'm preferring it to my Hp35s for general ad hoc number-crunching for its clearer display and simpler controls. It's really a design classic and getting one of these scratches an itch I've had for 40 years!
I ordered two units of the HP 15c CE in late 2023. Both units are from lot number 9CJ323. Neither unit had protective plastic on the keys or bezel. Given that your box had a plastic seal (as did mine) my guess is that your unit is brand new, not a customer return. Did you notice any abrasion on the bezel with a possibly matching abrasion on the inside of the plastic window of the display box? Both of my units had abrasions on the bezel and plastic window. I kept both units, but I may order another two units if I believe that abrasion is unlikely with more recently manufactured units. With the two units I received, none of the three small paper booklets with legal notices contained an English version. Based on the French version of the legal notice, I believe the English version appears on page 262 of the Owner's Handbook. In any case, I think the people who made the heroic effort of bringing us a new 15c did a great job and I hope they will consider bringing us a 16c as well.
I can conform, that the keyboard is really bad: Triggering or bouncing, if you like. But you can't believe your results. I often also have numbers bouncing, not only functions.
It really annoys me when you are half way through a video like this before they turn the device on! Come on, we want to see what the display looks like too! You actually get all the way through without switching the earlier comparison machines on at all! However I actually have one of these, and while it is very nice, it is undeniably expensive for what it is and they have missed an easy opportunity to add value. If you open the battery door (which is quite different from the original, so this is not an authenticity issue) there are a set of contacts for flashing new firmware. I discovered these are actually USB signals and the USB programming cable you can buy is entirely passive (not, as I assumed, a USB to serial converter). There is easily room in the battery compartment for a USB-C connector which would have eliminated the need for a programming cable and would also have enabled firmware that allowed the state of the calculator to be saved and restored to a file on a PC (like the Swiss Micros version can). Huge pity they did not do this!

Yes, I've had it happen twice so far in normal use 🤔 but both times I caught it
Got mine today. Will be USED every effing day! no storage

take a look at Eric's Video about recreating the HP 15C Handbooks:

I'll take a look later. Thanks!
