I've had 3 Logitech MX Anywhere mice and all 3 have failed, the first during the first year and was replaced by Logitech under warranty the second failed within a year but Logitech refused to replace because it was a replacement and the original warranty applied. Bought one more but that failed just out of warranty so never ever again especially at that ridiculous price. Apparently there is a design flaw, or at least there was, but it was enough to make me never use them again, great when it worked but should last lots longer than 12-18 months.
