So my wheels arrived last Wednesday as promised.
The quality is AWESOME. I had 2 wheels done (one in primer and one in black). I sent them two completely junk cores, and I got 2 excellent brand new wheels back. HOWEVER, the clear coat on the black wheel reacted with the bubble wrap, and I had to send it back. Koch's was very polite and even sent UPS to my house to pick it up - they said "we will absolutely make it right."
THANK YOU again to Loren for another successful group purchase! What's next?! :)
