A part of the review has been auto-translated.
The Chainsaw came with all the correct parts and even the instructions manual being all in Chinese, it was easy to understand the pictures to assemble it. Everything is working fine by now but the switch is only for on and off and doesn't increase or slow down the speed. When you turn it on it takes a pair of seconds to achieve maximum rotation and it has some kind of protection for motor or battery not to overheat or discharge too fast because it shuts down after around 10 seconds and you have to release the button and start it again. Motor could have more power. But it is enough for small works.
Probably the best in his category. That's a fast cut because it's one of the few that has a high-speed chain of 10m/sec. But it consumes a lot of energy and the batteries are running out too fast. He has a pot of oil for lubricating the chain, but the oil goes by flow, he has no oil pumps. The motor is Brushless whiskey and the body is strong aluminum.
