Really like this mouse
Reviewed in the United States on July 16, 2019
Original Review 7/16/19: What a great little mouse! It's a little smaller than my last but I'm sure it will feel natural in my hand soon enough. Love the near-silence! No more obnoxious Click-Click-Click. Lightweight and very basic, no side buttons, not even an on/off button. Didn't think I would like that at first, but that it goes into sleep mode is actually pretty convenient. Right or left click to wake it up. Seems the red light (underneath) stays on all the time, even in sleep mode. Feel like that should drain the battery... remains to be seen. Regardless, I use rechargeable batteries. For the price, this was a great buy.
UPDATE 7/22/19: The light staying on DOES drain the battery, it lasted only 6 days. Fortunately I use rechargeable batteries but this still isn't acceptable. Bummer, because I quite like it in every other way. From 5 stars to 1 star unless mine is just defective and Amazon replaces it with one that works properly. Meanwhile, I have to pull the battery every time I walk away, which is far less convenient than turning it off by a switch.
UPDATE 7/26/19 Amazon sent a replacement immediately, seems to work fine. Red light no longer staying on all the time, it goes out when mouse sleeps. Defects happen. Changing rating back to 5 stars.
UPDATE 8/21/19 As another reviewer said, mine also goes to sleep WHILE I'm using it. Not a big deal (for me) but still weird.
UPDATE: 4/27/20 Replacement still working fine. Rarely goes to sleep while actually in use. But just an added note -- this isn't an especially precise mouse, sometimes detailed edit work can be frustrating. Is otherwise fine for basic functions.
