very good but the shipping cost that's out there

Easy to locate part. Good experience

Good site everything does what it's supposed to do.

Excellent transaction, received item very quickly and it was a lot cheaper than any other online retailer that I was able to find, could not even find cheaper on e bay.

Bought an Autometer Ultra lite 2 pyrometer and it looks great. Autoplicity has the best prices on their products and ships their products very quickly. I will definetly buy from them again.
