Id check the availability of spare parts for it. There is a good chance it would be disposable in as much as if anything broke you wouldnt be able to replace it. Also bear in mind any warranty etc.
How cheap is it?
Thank u guys for your answers. of course I've decided not to take any risk.
I'm not launching a new career as a timber cutter. I need a chain saw to cut & trim branches of the trees that I have in my yard.
as per Breezer's question - the price of it is equals to about 116 pounds.
