I bought some parts. They didn't work on my bike. I asked for return authorization. They didn't answer multiple emails. I filed a claim with PayPal. PayPal refused my refund because I sent the products back via US Mail without a tracking number.
Dollar amount was about $40, and I wasn't going to spend $40 to ship products back to get a $40 refund. Still no response on refund from this vendor. They ripped me off.
