Performance is great. I might exchange it for a bigger size. Get these for anyone who loses their stuff. Also, I would like to have 2 devices with same watts fast charging speed than having reduced charging speed when 2 phones are being charged simultaneously. But with my second pair, I either started waling better or the design changed slightly and I did not need to be that drastic. I appreciate your support and thank you in advance. They fit great and Im sure theyll fit even better after I wash them. I can bend, reach and work comfortably. I definitely recommend the seller and the product. Just remember to rotate your steering wheel 180 when using it if you have a bar at the bottom of your steering while.
