Most Recent Reviews Didnt even make it trough 50 rounds by GIO619, Verified Owner, April 20, 2023

Most Recent Reviews Will come loose by Dachub, Verified Owner, June 28, 2022
And it will only get worse over time as you grip it. I had to return one that wouldnt torque anymore and just kept spinning. Good concept but doesn't hold up to what it needs to do, which is stay in place. Sorry, hard pass.
