Thoughts on the Neewer NW645II flash?

I’ve been looking to getting a flash lately, and this one seemed very interesting. It’s very cheap compared to the other 2 I was looking at, which are the godox tt350 and tt685 (not the II version). Anyone know if it’s worth getting? Particularly concerned about size bc I don’t want something massive, which is why I’m mainly favoring the tt350 rn but idk if it’s worth it. Any help?

I have a Sony a7c2 with a 24 to 105 as my main lens
