Smooth...

The ordering process was easy and the price of the product was fair. I was; however, disappointed with one thing. I received an email from Autoplicity for 25% off shipping but it would not work when I was checking out. I called the customer service number and the gentleman was not helpful at all.

My Order shiped next day, best price and best looking product I found on line

Easy to use with the Amazon account. All ok!

I'd like to make sure if they are all original Bosch and

It was a pleasure to do business with Autoplocity and would definately buy from again and or recommend to anybody. Item was shipped out fast with great packaging and communication was top notch.<br><br>Thanks again!

easy to shop

I saw nothing but good reviews and the money back guarantee, these together helped me finalize my decision to order from this site. I ordered just before the weekend started so I think it took my order a little longer to process. I was relieved to find that my order was shipped on the day I ordered it, It just took a little while for the email traffic to catch up. So far things have been good!!!
