I have it, Bought it a few years ago, Currently in the cupboard as a backup mouse, Replaced it with an Asus ROG Chakram, While the Spatha is a brilliant mouse, The wireless part of it gets old quick as the battery starts to lose charge very quickly after a while and you cannot replace it easily, It also tends to lose connection a lot.
If you are using it wired it's a great mouse, Downside is it has rubber on the left and right sides that will start to breakdown after a while.
Honestly if you are after a good Asus ROG mouse I can highly recommend the Asus ROG Chakram, Light weight, Can be used wireless with a much better battery, Charged wirelessly too, Can be used wired, No rubber parts to break down and feels great in the hand.
