I've had 3 sets, flatspotted one, and recently got a small piece knocked out small of piece from these. I agree they are the best wheels out. I have some welcome orbs on my set up now, i'm not liking them as much as my last 3 sets of F4's. I just ordered another set, but my fat ass wears these wheels down i guess.
That has literally happened on all but one set of F4s I've ever had. In the exact same spot too, the outer corner area. I actually posted about it on slap somewhere years ago and Lenny or someone actually hit ME up offering replacements. Stand up customer service quality as usual. The replacement set I got was great, but ended up having the same thing happen to them eventually a little down the road. Then a set I bought after that had the same happen within the first week too. DLX said if I ever have problems again to contact them whenever to let them know, but I decided not to, I just didn't want to keep bothering them over something this small and feel like a hassle, plus the wheels still skated fine, the missing chunk doesn't effect the ride of the wheel at all. It has happened on just about every set of F4s I've had since then somewhere down the road though, but i generally don't pay too much mind to it unless its a huge chunk. I used to have gnarly gear OCD a couple years back, but have since learned to just stop caring as much. I used to freak out over stuff like this or over dirty griptape or little board chips, these days, not as much.
