I took a cracked Volk to them to fix. It cracked the same day of the 1st repair, same day of the 2nd repair AND same day of the 3rd repair.
After 2 tires and a lot of stranded on the highway time they told me to try getting it fixed elsewhere as they could not fix it.

They didn't offer me a refund despite the fact that their work is guaranteed.
They were very nasty and unprofessional.

I ended up having to take them to court.
It was a nasty ordeal and in the end I spent about the same amount of money that I would have spent to get a new wheel.

While others may have had good experiences with them mine was horrible and I would not recommend them to anyone
