The problem with Chinese knockoffs is the quality control. If you bought 5 chainsaws for example that were the exact same, I would be willing to guarantee at least 90% of the time only one would start as advertised. One will be so shotty in its build it won't start, one will have a bad carb, one will need its carb tuned and one will be missing parts. I've been a 2 cycle tech for years and it never fails with the cheaper knockoffs. Now, when you can get them running, they are relatively solid and you can usually find replacement parts that fit from Stihl or Husqvarna but it's still rolling the dice. Also, they are never what their power says. Again because of qc in China it will be stronger or weaker than what it's knocking off. Next issue you're gonna run into if you're in North America or Europe is is the fuel mixture. If it says 32:1 for example and you're in the US, you're going to deplete the life of that saw with that mixture as the fuel and oil standards in China are significantly lower. So when you run an ethanol free fuel and a decent 2 cycle oil you'll be doing so without knowing the actual engineering standard for that saw in the western world. Where people have good luck is finding out what saw that's knocking off and using that fuel mixture. Anymore it's 50:1 to get the most out of it and that changes further if you're running like Amsoil in it. If you have the money, buy quality. If you don't, at least get one of the bigger Chinese brands like Proyama, Wild Badger, Farmmac, Salem Master, Supmix, neo-tec and even some Vevor. I've had good luck with all those as far as repair and finding quality replacement parts from more reputable brands like Stihl, Husq and echo. You're going to be told to stay away but your budget is what it is and there solid options. Just be prepared to potentially have to send it back for replacement right out of the box. Lastly, if you don't already know, learn to tune a carb and get a universal carb adjustment tool kit from Amazon
