Test drove the 2 inch evolution last night myself, coupled to a white magic pro 1200 hv, not just a little test, but a long long test, an all night test. Its a mans wand thats for sure. From my personal experience the evolution is a wand that only a man would use, only a real man would own one. Big wide sweeping swath, light weight, and for some reason smooth as a babys a$$ when you use it, made me feel like a giant. Cut the time out last night by almost two hours (thats about 25 percent). yup truely only real men will own this wand. By the way....we were doing commercial glue down and some other kind of commercial with some kind of thin pad under it. ( I dont know that much about kinds of carpet) I kind of like the idea of the plastic replaceable wand lips it has as well, and also how light it is.
