Don't be fooled
My experience with 1A Auto has been absolutely horrible. The product doesn't work correctly, it's actually worse than the one I wanted to replace. I tried to contact 1A Auto via email and phone about the issue with no avail. I'm beginning to believe there will resolution to my issue, nor will there be a refund for the faulty product I now own. With treatment like this, I'll definitely NOT recommend anyone to purchase anything from 1A Auto. Thank you for my very bad online experience...

Great customer care
I ordered an AFM from these folks. It was a defective unit. Rhonda shipped me a replacement immediately (it arrived next day). Any company will be rated well if there's NO problem...I measure companies by their service when there IS a problem. Service & replacement part were A-1 for me...tops in my book.
