Query: Works great until it breaks

Bought two of these for Christmas, one to use and one to give as a gift later in the year. Began using right after Christmas. It was fantastic, worked just as advertised and shown in the video. In February it stopped working. It acts like the retracting mechanism broke. I began trying to get warrenty service from Oster. No luck.In the meantime I began using the second one. It was fantastic until it broke two weeks later. Same problem. Now I have two broken openers. I guess I will go back to a cork screw, primative but effective.I guess this post brought good karma. Got an email today notifying me that a replacement was being shipped. Will report how this one goes.
