I am very disappointed in this product for which the quality is not at the rendezvous. The screws of the sleeves are not provided. Once set (securely with screws suitable), the sleeves move in their housing, which is quite annoying when using. More seriously, the teeth are twisted from the first use making relatively useless tool. I'm not yet arrived to redress and therefore uses more this tool. Given the price, I do not have that choice and rather orienterais me to the original product finally just more expensive.
