Did you ask hongfu to just send you a new rim rather than demand a refund?
I ask because I have had very similar experiences, with Farsports albiet, and a UD finish delaminating and they replaced the rim and covered the shipping.
They did offer to provide a new rim. But they would never tell Paypal or myself how exactly this was going to work. They just kept telling me to drop the PP dispute and they will take care of everything. Paypal also requested how they were going to rectify the issue. But no reasonable answer ever came back from them.
You were fortunate with your situation it sounds. That is good for others to hear. Guess I had the bad side of the equation this time around.
I only wanted them to refund the cost of the 1 rim cost, not even shipping, because I did get one other rim. I think that was reasonable.
I know they are half way across the world, and I'm just telling people and want to reiterate, if you want follow up support/warranty, it isn't going to happen. Plain and simple. Buy wheels/rims from them with the assumption that is all she wrote, end of story, anything that goes wrong, your problem.
If you do want support/warranty, buy from a reputable company in the US/your part of the World. There are plenty, they will take care of you, people like Boyd etc...which I've owned his rims previously. They have fantastic support/customer service and a descent product for the price.
The real tragedy was the wheel build issue I had. I don't even want to go into that whole mess and what it cost me to fix somebody else's mistakes who built 3 wheels wrong...live and learn my friends, live and learn. Should have rebuilt my 303 FC Zipp tubies with new hubs and been done with it...haha...
Plus, I need to learn to build wheels myself. I do all of my own maintenance for everything, except wheels. It's the only mechanical thing I've never tackled...guess that it is time to learn also.
The rims/product from HongFu, or any Chinese maker have be fine. Want to make that point also. They ride good, laced up well, have been good performance-wise comparable to any other wheel I've owned. I train/race with them, no issues at all.
My post was really just a reminder/lesson to people that if you think you are going to save a buck, in the end, you might not. Just buy the wheels, and if something goes wrong, buy another wheel and just eat the cost. Or you can try what I did and hope for the best.
Even after the refund from PP, props to them for that, although it isn't what I really wanted, and the wheel rebuilding, it cost me quite a bit of money than my first set of wheels from China did. That is the real lesson. On the initial purchase, you might save money, but if there is any problems like I had, forget it. All the cost is coming out of your pocket, any savings just vanished unless you have PP back you up.
Also, I wouldn't trust any, but a few wheels from any company, big brands etc, to be correctly built out of the box from China. You should take them to a good wheel builder and have them tested for tension/true etc...before riding them. You would be surprised, even with so-called well known wheel builders in the US, how they can f-up a set of wheels. Even more money out of pocket!!
