But as I got used to the phone, I found myself liking it more and more, to the point where I ultimately removed my SIM card from my iPhone 7 (AT&T) and am now using the Moto G Fast as my primary device. As comfortable and ergonomic as the 570. I bought a size 5. I am a 7-1/2 and ordered the 8. Update: I tried it for a week, both on-road and off-road, and it holds solid as a rock. however, they simply do not last and for the price B&Os customer service and warranty assistance is exceptionally poor. I am using this mouse in a 32" 1440p 240hz screen at 400 dpi, yes 400 only. at least it is precut so its easier to apply. And they come with vinyl ear cups, instead of nasty velour. Bought this for my husbands AirPod pro case.
