Alufelgen's are nice looking wheels no doubt, but I have not been impressed with their durability despite the claims they are super strong wheels. Two of my rims have bent so far. When I say bent, they are/were out of round to the point where they could not be balanced. There is no physical signs of damage (they still look new).
I avoid potholes like the plague as well as any other road imperfection that might cause me/my wheels problems, but admittedly I have hit a few road imperfections that were jarring, but I would not expect the rims to have bent so easily if this is what caused it esp since there are no physical signs of impact to the tire or the wheel. I do not live/drive in the city, I'm in suburbia.
I will say Alufelgen stepped up to the plate and swapped out of one of my wheels, so from that standpoint the company backed their product.
