Just walk away. Hit back and close any tabs regarding buying from this company.
I bought an alternator and it failed (outputting a whopping 0 amps) within 4 days of purchase.
They aren't returning my calls, so I will be forced to use eBay buyer protection to get my money back...
Check out all their fake reviews too! I mean WOW! Just how desperate ARE they? I hope they get run out of town.
