That item number wont work for me, likely because im in canada.
Most all of the 52cc chinese saws are a clone of a japanese Zenoah 45cc pro level saw.
They come in 45cc, 49cc and 54.6cc. They are sold as anything from 45 to 68cc lol.
The "52cc" ones are really 49cc, they're alright but the next size bigger is quite a bit stronger and the exact same weight.
Like posted above some claim to be 62cc but they are not. Proyama sells a lot of them on amazon. The only proyama saw worth getting is the "68cc", it's really 54.6cc, the others are 45cc with long bars.
In canada the best running one on amazon is the supmix 6220, it's 54.6cc. The supmix runs very well but has cheap, thin, easy to break plastic.
