I have seen it in action and the barrel warps because it is welded. Then your leaf wont reach the blades. It is poorly designed. The only trimmer that really works and is actually worth the money is the Tumbleweed. It is also called the Samurai.

I have seen this machine do 8 lbs of purple in an hour.
The local dealer in Humboldt is Trim Scene Solutions 707-223-3873 They are the local experts on these machines. They can get you anyone you want but they only recommend the Tumbleweed. They have seen them all and this is the one they recommend and rent out.
