About what you would pay from Ali express but next day shipping and Amazon warranty.
$30 off with coupon.
PAW3395 optic sensor, seems to be a pretty decent one.
Even cheaper from here - $50 (but slow delivery) - https://www.amazon.com.au/AJAZZ-AJ199-Lightweight-Programmab…
any 60g mouse with a 3395 is worth checking out. $59 makes this a steal
edit: seems to be a g pro superlight clone, for those looking for some reference
