WYNGSProtective Case for Hewlett Packard HP 10BII Plus/HP 17 BII Plus Financial Calculator in Black

Let's get this out of the way, HP is price gouging us something fierce with this calculator, but...It's a really sweet package! The collector's edition box (the black one inside the retail box) is very pretty. It comes with a very nice paper manual. The calculator itself is a big improvement over earlier versions of the 15C: its faster, has more memory, and fixes all known bugs. It even has a "secret" 16C mode, though reportedly, it has some bugs that I didn't encounter. The keys are nice and crisp. The WYNGS case is nice, but not an exact fit. It is an exact fit for an iPhone 13, so we can guess what it was originally intended for. Still, it's better than the flimsy leatherette case that comes with the calculator.I won't go through the features of the 15C. If you're buying the collector's edition at this inflated price, I assume that you already know what it is.Keep in mind that SwissMicros produces (at least) two "clones" of the 15C. One is the same size as the real one, the other is credit card size. Those who have them rate them well, but they cost even more than this genuine collector's edition. I have not personally compared them, but be aware that they exist when you make your choice. I chose the original HP, so that should tell you what I recommend.

Delivered quickly and as advertised. Great product.

Nice case, sturdy
