    Clamp broke before first use. Schumacher send me a replacement part at no charge.
    4 Stars
    Clamp broke before first use. Schumacher send me a replacement part at no charge.
    The black plastic battery clamp literally flew apart during the initial battery charge. I plugged the unit in to charge it for 36 hours, as the instructions specify, and as I was walking away, I heard a snapping sound and half the handle, spring and plastic pieces flew across the room. I suspect that the plastic clamp was brittle and that just the pressure from the spring was enough to break it. I had just opened the box and hadn't even removed the clamps from their resting post by that point. Ok, it's made of cheap plastic instead of metal, but things happen even with the best equipment at times. The worst part of it is that Amazon says it can't be returned, and to contact the manufacturer. So... I called Scumacher and told them if they can just send me a new clamp I can replace it myself, saving both the expense and time of returning this heavy unit. They asked me to send a photo, which I did. It's now been two days and I've heard nothing but crickets. If they come through I'll revise my rating, but for now I have nothing complimentary to say about either the product or the support I'm receiving from Amazon or Schumacher.UPDATE: Changed my rating from 1-star to 4-star after Schumacher sent me a replacement clamp at no charge. Still a bit of an inconvenience to change the clamp out, but all's well that ends well. They did the right thing. Deducting one star for the cheap plastic clamp design, but since I will mostly be using the unit for the 12VDC lighter socket and not to jump start vehicles, this unit looks like it will work well for me. The 22 mAh battery is bigger than some of its competitors, and that's what's most important to me.
