Sharp xe-a21s 3

It's a basic little cash register and works well for a small retail shop as long as you don't expect it to live up to the claims on the box such as SD memory capability, integration with Quickbooks Pro, or working on your computer if you have anything newer than Windows XP.

Unfortunately, this register is three years out of date and so a lot of their functions no longer work. You can't use a SD Memory card larger than 512 MB (I defy you to find one of those still for sale). It does not work with the current version of Quickbooks Pro. And their software, which doesn't allow import from a spreadsheet or anything, is so outdated that it doesn't work with Windows Vista.

Their tech support was okay, but got a little short with me when I pointed this out.

Apparently there are no upgrades for any of these "features," rendering them useless.
