Easy wireless connection to an Android phone using the phone app described in a small printed user guide. Mine didn't come with a CD, software, or instructions on how to connect it to a PC.

The photos show an increasing close-up of a US 25 cent coin, while another shows a close-up of dirty skin. It takes practice to frame and focus on the subject. It would be nice if the focus wheel was easier to turn by holding it with one hand.
