Thank u

so far, will see when part arrives

please send tracking info

it been great..............

You shouldn't have the card scanner so frantic in its attempt to record the payment card, it's disconcerting to the buyer and may cause them to change their mind about shopping with you. Especially with all the identity theft these days. Just something to consider. Thank you for having my product available.

Ordered my CTEK battery Charger on Wed night and received it on Fri morning. Super fast shipping. Will definitely buy from again.

It was okay. Product doesn't completely look brand new, but I hope it does the job.

The price is good, easy to fill out the required information, I hope the shipping is fast, paid for 2 days over night, need the part now.

I searched the entire web looking for the best price on my item and found that Autoplicity beat everybody else in price & quality. Search no more!

Easy checkout and could actually FIND the part. The only other thing I would want is a install picture. Just to make sure I was buying the right item.

Easy ordering with Amazon.
