This is part of HP’s Splice series of calculators and checks just about every box I could hope for in a calculator. It’s got brilliant red bubble LEDs, the keypad is sharp and responsive, and it’s an RPN calculator which gives it that edgy charm. Perhaps a scientific focused model would be better to use on a day to day basis, but I don’t mind it so much for what I usually do.

This one has been barely slightly modify with some copper tape to replace the one sided battery contacts for the rechargeable battery it’s intended to use. I highly recommend the mod I documented in a video, using AA’s instead makes it much easier to power and you can remove them for storage without worry.
