Value for money


Does feel great and it works very well. I am very happy that I decided to choose this one over the profissional one which is so much more expensive. The only difference is that this one isn’t made of solid steel like the other one but honestly you will not feel that it wasn’t. I thought it was metal till I read on thier own website that it is not. I don’t know what it is made of but whatever it is made from, it does not feel plasticy or cheap. Buy with confidence it works very well
