The mouse lies perfectly in the hand, as if cast in a mould. All keys work well, not quiet, but not very loud either. I'd say it's pretty standard for clicks. instantly connected to a Win10 desktop, which is nice because I couldn't find any drivers when I googled. I can't set up the buttons like my fancy wired mouse, but I don't care with this one, I only want to use it when I'm sitting at my computer desk or working from my bed. Someone complained that the side buttons are too far back, but I like them. My other fancy gaming mouse has it further back and I have to bend my thumb to reach it, but this one is pretty easy. I love the charger. I'm tired of changing and charging batteries for my latest wireless mouse. that's the main reason I got this. super function! I absolutely hate the batteries in them. If the light worked on this kid I would give it 5 stars. not a big deal as it doesn't affect how it works but just thought it would look cool. and maybe make searching in the dark easier. I've included photos of the USB charging cable, which is probably one of my favorite features. Now that I've been using it for a while it seems to last about three days of very heavy use before emptying. If I were smart, I'd probably charge it every night before I go to bed. I'm also not sure if anyone cares, but I took a picture of a lap table with a small wireless keyboard, a mouse pad, and then this wireless mouse. I don't know why I didn't think of it sooner. I used to get back pain from spending so many hours in front of the computer. I couldn't find a decent office chair to save my life. I literally spent three days researching office chairs and they were all crap. I use a 55 inch 4K TV for my computer screen and now I can just sit on my bed with my kneeling table. , mouse and keyboard and I feel very comfortable for several hours. Edit - I figured out why the lights don't come on. For some reason the power button was stuck halfway between on and off. I don't know why but the mouse still worked but the light didn't work. Just wanted to mention that in case this happens to anyone else. the thing works amazing now
