A faulty timing kit from them destroyed my engine. They offered to warranty the $100 part, but won't do anything about the $4,000 engine it ruined. You’re taking a big risk with their 'budget' brands.

If you know exactly what you need and don't need to talk to a human, this is the way to go. Just double-check your part numbers because their 'fitment guide' can be a little buggy for certain model years.

The absolute king of prices. I saved $400 on a full set of rotors and pads compared to the local stores. The shipping was surprisingly fast, and I got the cool magnet for my toolbox. Can't beat the selection.

Great until something goes wrong. There is zero human customer service—you have to do everything through their automated system. If they send you the wrong part, be prepared to pay the shipping back yourself, which is a scam.

The best prices online, hands down. Just be careful with shipping costs if parts come from different warehouses.
