Nice, it's worth its money. Just like a friend mentioned in the comments, it definitely needs a different chain, maybe even a blade. I would like to know which blade and chain the friend bought that would fit this machine.

I bought it but the chain doesn't turn. After trying, it finally started to turn. I cut two logs and the chain loosened. I did the same several times, same result. Eventually, I decided it's not worth it and returned it. Note that the construction is cheap

I saw the review of friend 1 and it was the only one and I decided to buy it compared to the conflicting reviews on the other chainsaws. The only thing I changed was an Oregon blade + 2 extra chains that I bought. The machine is amazing. Oregon lubricating oil for both chain and mixture. I cut wood non-stop until the gasoline runs out. I refill, have a cigarette, and melt it again. Really, compared to my friend who has an Oleo Mac, mine stopped after 10 minutes in terms of consumption. I highly recommend it.
