My friend lent me her Andis AGC 2 speed super duty clippers. I used it for a hair trim for Toto and it worked beautifully for the first time try. So I want to buy one as well. But it's a bit too pricy. I went to Amazon and find so many choices. The Andis 1 speed clipper kit looks quite nice. Is it durable and good? Do I need a 2 speed clippers?
