I don't know much about electronics but maybe that's a good thing. My rating may be for the "average user". I've wanted this for a long time and finally ordered it. I am very happy with it. It charges from standard USB to microUSB and lasts up to five days (according to specs) if you use it for two hours a day. I don't let mine go that long. I have it plugged into my laptop and when I use it for a while/a few days I plug it in. To use it you have to activate it, which is very simple. Just a little button on the side that turns blue when on. Then just use it as you imagine. It works well, easily clicks items, scrolls as if using your finger. I use this to cut/paste and edit photos. To do this, you must have a detailed pen. It comes with a pouch and a carry handle - I don't use either. In general I am very satisfied with her. I use it more often than I would have thought. I recommend it to you without hesitation. Enjoy yours!
