The Taigen metal tanks are pretty darn good. At least the shermans are. I have a bunch of them.
Already said what I think of Matomart. and yes their shipping is very slow. ITs too back you got treated that way. He could easly have figured out what the problem was by saying send me a few pictures to show what your talking about. Someone like that either knows he screwed up real bad and doesn't want to help the customer, maybe because he no longer has the IR model of that tank, or he is mentally ill. When I have encountered attitudes like that without rational it usually leans toward mentally ill.
