Unfortunately, the experience I had was not the best.
A few years ago, I bought 2 Kelly 7218s controllers without any problems.
Last year I bought a qs205 5T engine with a pro SM rim, they sent me a 4t version with the stock Chinese rim.
I contacted the seller to inform him of the error, I've been waiting for a response for 3 months, he didn't have the honesty to respond, not even to say that he regrets the error, he didn't suggest exchanging it for the product I bought and he didn't offer to return the amount charged for what was not send, basically respect 0. I will not buy again.
