I've long argued that low price doesn't always equal low quality. There are a number of low-cost knives that offer excellent value for money: for example, I must have half a dozen of the Mora range scattered around the place, including one right in front of me at my desk, and I use them more than all my other sheath knives combined. Low-cost firearms are sometimes more dangerous to the user than to anyone else, but there are some that aren't bad at all.
The same appears to be true of chainsaws. I normally wouldn't trust a cheap chainsaw in comparison to brand-name, supposedly higher-quality units; but this user found differently. He offers an extended review of what he learned.
For someone like me, who doesn't need a chainsaw on a regular basis but wants one handy in case of emergency, that price point makes the Chinese model a viable proposition. I'm going to get one and see how I like it. (I'm also going to make a point of getting training in how to use it safely. I've seen too many really nasty injuries from chainsaws to take them for granted.)
