I'm impressed for the price, it did overheat on me and needed to cool down for about 20-30 minutes, but it ran through oak very well for what it costs. Overall I'm pretty happy. There is no guard near the exhaust which sits next to the bar, be careful about that. I've got a nice blister on my ring finger from that lesson.
Assembly was a pain in the neck, but livable. The clamps for the bar aren't flat, nor were the hex bolts long enough to hold them. Picking up new bolts and grinding down the clamps flat, then I will update my review after I get to use it. So far, you get what you pay for and I should've invested more.
Update: got new bolts, these are 5/16-18 3 1/2in bolts and don't fit. No idea how this piece of garbage is threaded, but I cannot find bolts for it. Going to try to return the product now
