Absolutely brilliant service from this website. I was unsure if this was a legitimate site because I couldn't find the battery I needed anywhere else online but it was listed here on mk3.com and at half the price I expected. So I took the gamble of ordering because I didn't stand to lose that much if I was ripped off and was expecting it to be an aftermarket battery at best but I received a brand new autel battery at a very good price. I even ordered 2 by mistake and without prompt the customer service agent quickly contacted and refunded me for the extra 1 I didn't need. Not only was the service outstanding but the battery was delivered within 2 days. I've now fitted the battery and it works as expected. Don't hesitate to order from these guys they're the business. I rarely leave reviews but for these guys I just had to. 5*
