I own over a dozen Park Tool products and had a problem only once. I bought their EH-1 wheel stand and was disappointed by poor unbalanced welds which included excessive splatter and unfinished burrs. Usually I ignore minor defects with tools but this part was unacceptable. I sent an email to Park including photos but they never responded so I returned the part for a refund. One bad purchase out of 15 isn't bad, but damm I really wanted that tool.
