I consider myself pretty tech savvy. Got this. Instructions not well written for set up. So I made assumptions. Charged everything. Then could not get to pair with my laptop. After stomping around frustrated and pulling box to send back. I did one last read of instructions. Ohhh the BASE of mouse has a very inconspicuous compartment. Opened plugged in and worked perfectly! Like it. Lighting good. I work late at night and allows me to have lights off and still type. Would have preferred more shallow button but not bad. Recommend more obvious compartment for USB or arrow that says "open this”.
