I'm a lifelong fan of HP calculators. I have a 15c in front of me right now that I've had since the mid-ish 80s. Still works perfectly.
But the 15c 'Collector's Edition' had some issues, and I wonder about the build quality and reliability of this new one, too. Plus: my guess is you can get an original working 16c on eBay for less than this is going to cost.
Honestly, it pains me to say it but I'd recommend a SwissMicros DM16L instead: https://www.swissmicros.com/product/dm16l
From what I’ve seen, eBay runs more than this for a used original. My collection of all Voyagers ran about $200 each a few years ago.
Why would that pain you to say it? (Honest question, not leading.)
The prices for all kinds of vintage electronics have shot out like crazy. Calculators, computers, cameras and other stuff are super expensive.
