So, I have both a Seaspray from China, and one I bought through Kapow Toys here in the UK. There's definitely differences between them. Right off the bat, the plastic used to make the pylons either side of his head is different from the 'official' one. The details are softer, and the yellow is a lot deeper and plastic-y. The paint is a lot sloppier on the Chinese one. You can kind of see it in the picture above, but here's a better look. The ball joint on the Chinese Seaspray appears to be too long, meaning the arm part of his hover skirt doesn't sit flush with the leg part, unlike the 'official' one. And finally, the eyes on the Chinese one aren't painted in. Also, the techspec card that came with the Chinese one had Gnaw's specs on the back, while the official one had the correct specs for Seaspray. In my mind it's conclusive that the Chinese one is a knock off.
