Only just getting to know it, but easy to set up and use. No problem using SD card standing alone from computer. Easy to connect to laptop. I have only used a Vista machine so far. Documentation refers to Windows 7 and 8. I hope it also works with Windows 10. I have not tried that yet. Slide carrier a bit fiddly to open and close, and instructions on inserting slides and the carrier could be clearer. I note that some other devices have slide carriers which only take 3 slides. This one takes 4 which is good. I will be seeking to buy a second carrier. The USB cable is a bit short. Highly satisfactory so far.
