Bests & Worsts Reviews from Amazon

I ordered the clippers. Received them in 2 days. Plugged them in and got a green light. When I turned them on they worked, but if I turned the clippers sideways or upside down they quit. It seemed as if the battery wasn't making good contact. I ordered a replacement and received it in 2 days. The second pair doesn't work at all. No light comes on. No charge. Sent this one back and asked for a refund.
