Information? Not from personal use- however, these show up under all kinds of "go faster" names, but are all the same tinny copy cat of a Japanese saw that was of higher build quality.
In my opinion, you are saving money in your head only, buy cheap and long lasting quality do not go hand in hand- generally these seem to be the cheapest build, lowest quality of the copy cat saws available- lower even than Farmertec and that is saying something!
Reviews you see are usually glowing because they simply do not publish the bad ones and reviews are posted soon after unboxing and initial start up- not after a season of wood cutting (if the saw lasts a season!).
