Title: All 4 failed within one year!
Review: I bought my first two last year for two of the cars I dont use often. Within a a couple of months both of them have failed... so I thought maybe I got a bad shipment. So I stupidly purchased two more to replace them... Both replacements failed within 6 months... worse yet, one of them still had a green light on like it was working!! I didn't know it was feigning proper operation until I tried to start the car... with a completely dead battery!DO NOT trust the other 5 stars here! All of them are short and claim they liked the product for having STANDARD features!! Hire better writers for your sham reviews, Black and Decker!This is the absolute worst product I have ever purchased!!
