I just got a Z400 from them, and things are not going well... It's a brushless, and the motor shaft was bent... Now, the li-ion and li-po that were included aren't charging. I assume the problem is with the crap wall charger, but I don't know for sure yet. I'm waiting for their reply. I have to say that shipping time was amazing...China to Canada in a week. That's more of a credit to our postal service though...
