They're good. Basically the same as Tokyo-Marui tanks but with another name slapped on. That is, they come from the same manufacturer in China.

I don't own one but have handled them and have read the numerous posts here about them and the consensus seems to agree that they are the best bang for your buck in 1/24 scale.

I'd suggest reading the back posts on them or doing a search for relevant subject matter using the search forum function at the bottom of the main page--should get you a lot of hits.

Only reason I don't have one of these tanks, and this is a good reason, is that I like the larger scale of 1/16 and they're just too small.
