Bests & Worsts Reviews from Amazon

I've been looking to purchase a new Jump pack for use in the shop and narrowed my selection down to either the Clore JNC660 or the Shumacker ProSeries DSR PSJ-2212 The reviews were about equal on both so I decided to get the JNC660 Well, I just received the JNC660 today and it is defective right out of the box. I plugged it in to charge and the amber led that is suppose to be lit does not indicate it is charging. The Green LED does not show it is fully charged either. I verified my power cord has power from the outlet; even switched to another cord. Disappointed; I guess companies no longer have QC on their products. UPDATE: Feb 04, 2014 After realizing that Amazon will not accept returns on this item, I contacted Clore Automotive tech support and explained that I had received a defective jump pack. I reviewed with them the various items I had checked to confirm that it was indeed defective. After they confirmed that I had purchased it via Amazon, they shipped a new JNC660 to me along with a prepaid UPS label to return to them the defective unit. I had the replacement unit in 5 days after contacting them. The replacement unit works great. Clore Automotive gets 5 stars from me for making this disappointing defective unit right.
