If you wonder why any positive reviews referring to customer service or communications are obviously fakes because -if they merely did as advertised, there wouldn't be a need for communicating with these useless hustlers. A 1 day turnaround as advertised, why would anyone have to call them. They can't communicate since they never ever answer their phone. Before getting ripped off by these scammers, try calling for yourself. They claimed to ship my part overnight than 2 days later asked for my address. I saved all the emails of these embarrassing con-men. It took 5 overnights and 2 weeks to get back my part was untouched. I sent it back, simply cuz my customer is now paying the auto storage and has affiliates in the local area, but need a reason to collect reimbursement. All they had to do was as they advertised. They can't even show a test result or mail a letter
