No more blisters!
“I used a vacuum suction cup extender for several months and found it terrible. This clamp and mount completely transformed my experience. I can attest that its quality matches that of a $350 branded product, yet it costs only half the price.”

Great tension control
“The calibrated springs are legit. I worked my way up to 15lbs. The TPU pads at the bottom are way softer than the hard plastic on my old device.The overall quality of the bracket and clamp is excellent! Plus, the clamp is solid inside, so it won’t break no matter how much force you apply.”

Best value bundle
“I was about to buy the stretcher and clamp separately from two different sites until I found this. Saved me a ton of money and shipping hassle. Highly recommend.Moreover, the stand can extend up to 26 centimeters for maximum exercise length—this product is fantastic!”
