My experience with autoplicity was great unfortunately the shipping service(Fedex) was lacking and made the process less pleasurable.

thank u

Quick and easy order. About half price of relay I just bought to get my generator running. Glad I didn't buy more at the auto parts store.

Very good no problems!

Good thanks

Fast shipping, install instructions were clear and precise. front cover fit perfect. No rubbing. I would recommend.
