Exactly what I was looking for at a very reasonable price! Makes entering numbers into documents very easy. Easy to use, just insert the batteries, connect the USB cable to your computer and you're done. It has an on/off switch, it's very light, I like it a lot more than a cord, and it works great with my Samsung laptop and work computer. Both have Windows 10. Entering numbers is much faster and I'm updating the phone list so it's perfect for this or anything you need to enter numbers quickly. I highly recommend it. The USB is in the battery compartment as someone else pointed out in their review.
