Endgame Gear is the new kid on the block, and its first mouse weighs just 70g. Over the last year or so, mouse manufacturers have been on a mission to make their mice lighter and lighter. Endgame Gear is looking to capitalise on this with its first gaming mouse, the XM1. Weighing just 70g, the XM1 is right up there with some of the lightest mice you can get, and unlike the Glorious Model O or Finalmouse Ultralight, there are no holes cut into the mouse’s shell. Priced at £53.99, is the XM1 worth buying?
