My go-to calculator has been a Casio fx-260solar. It's not a high-end scientific, but it does the basics well. It's also nice and small, turns on quickly, and runs in lower light than my old TI-36X Solar. I just got a new-in-package one on eBay for use in my basement workshop.Turns out, though, that this new one is slightly different than the other one. It's not the completely new redesign that Casio did that has the weird patterned/textured body. It's just very slightly different. The length, width, and thickness are all slightly smaller. The cover is a poor and too tight fit. The original is made in China, the new one in Malaysia. But the worst offense is that the keys are the awful soft keys. Ugh! So awful that I can't use it. I love using the original, though.So I was wondering if Casio would have actually spent time doing this slight (and worse!) redesign. Why make new molds for the plastic? Why go from China to Mayalsia? (pre-pandemic). Or if this might be a knockoff? (Attachment Link) (Attachment Link) (Attachment Link) (Attachment Link) (Attachment Link) (Attachment Link)

While looking around for more clues or an answer to this mystery, I stumbled upon this image which shows the same two variants as in the OP: https://casio.ledudu.com/images/calculs/casio/machines/zoom/fx260SolarX2.jpg found on https://casio.ledudu.com/pockets.asp?type=927&lg=eng
