I bought 2 receivers from China. One of them proved to be a lemon. (defective) The company didn't ask me to weigh the package but they did ask for a video of the rx not working. So far, so good. I also sent a photo of the shipping envelope to prove I bought it from them.

Their way of refusing to replace the defective rx was by claiming they were unable to find my order number. Even "Winnie" couldn't find it.

Lazer Toys replaced a missing part immediately, at no charge.
