We pulled all the carpet and pad in our home in order to restore the wood floors. I bought the 4V ZipSnip Cordless Electric Scissors in order to cut the carpet into strips, that I then rolled up and carried away. They were amazing, much better than I would have expected. The charge would last long enough to do about 200sq feet, and by the time I had rolled that amount, it was recharged and ready to go again. I have been in residential Construction all my life, and I have remodeled several houses by my self, I wish I had known about the 4V ZipSnip Cordless Electric Scissors years ago. I Highly recommend this product.
