Did not try yet, but quality looks very good! Two layers of silicone gripper on the inside, can’t wait to use them!

Very Good Quality for the Price and Very Fast Delivery

in the beginning I thought it was too large, then I fit it on and realized that it's for calf muscle extension diameter hence it fit perfectly 💪🏻 took just 6 days to arrive

Great! Fast delivery, serious seller and great material really well done!
