I'm not knocking the seller, but they admit that the surface is grainy, but post pictures in a very low resolution, so it's impossible to tell just how bad it is. But at $24.99 USD, I'm a bit suspicious. I'm not mentioning them by name on purpose, but it seems like a case of buyer beware, I'm not opposed to some work,but the last 3D printed kit I bought left me a bit disappointed and with all the curves and angles, it tool a lot of the fun out of it. Am I over reacting?, they offer some subject matter I'm interested in, but I'm not interested in wasting money.
