I had one set and was happy enough to buy a 2nd set. Unfortunately, the front rim on the 2nd set cracked when I was installing a tire.
That would have been bad enough, but then they tried to be cheap and offered to send me a replacement rim, not a wheel. When I asked for a new wheel instead, they tried to get me to pay $60 for it. Instead of playing around with them more, I asked for a refund through AliExpress instead.
Manufacturing defects happen, but for them to try to scam me instead of solving the problem wasn't very nice.
