content: I would not buy this product again. The gear box housing is made of plastic and breaks very easily. Just look at the pictures that people have uploaded. I didn't use for the first year and a half then after 1 hour of total use the gear box cover broke just like so many other people. I called customer service and they told me it was out of warranty. Do your research first and don't buy. Fortunately I can buy a metal gear box housing on Amazon. What doesn't Amazon have. :)
