On first impressions it looked like a nice, low price saw, however:
The petrol filler cap leaked unless very tight, so tight that it would pretty quickly break the sealing ring
Under medium load the engine started to fail and then quit (after the first hours use)
The recoil mechanism failed and would not rewind
Although a 52cc saw the power output when it was running seemed poor compared to many much smaller engine saws I have used. Fuel consumption was poor as well, better made, more modern engines are much more fuel efficient.
Be aware that the chain is Carlton brand (not up to Oregon spec. and the bar is not Oregon either)
I say what a shame because with a little more attention to quality it would be a nice piece of kit, it handled as well as more expensive brands.
