Will the OSleeve protect my skin from pinching between the smart ring and a barbell (or chin up) bar?Updated a year ago

Yes. One of the biggest problems we experienced when wearing our smart ring while doing weightlifting was the pinching metal-against-metal which meant our skin lost the game (not to mention scratches on the ring). This not only made it uncomfortable but increased the number of blisters we experienced.

After using the OSleeve, we found discomfort decreased (the material naturally cushions) and blistering of the skin was minimized (it also provided a slight amount of 'grip'). However...this is all in proportion to the weight. 

If you're crushing weightlifting goals and the pressure between your vice-like handgrip and a heavy bar is just too much, natural physics takes over and your skin will likely blister anyway...perhaps not the best for your smart ring either. Use common sense here.
