All as described by the seller, the shipping was a bit long, I have been using the tool for 2 weeks and it increases the hand strength considerably, 60kg is almost impossible to pull, I was really surprised
I'm not sure about the durability on a large weight. But on average it works fine
Congratulations great product, I am very, very satisfied. Fast shipping, well packaged with tracking code. I tested them all, they worked first. I intend to buy more. I highly recommend the seller and the product !!!
