      Works like a charm.
      Color: Silver
      Our last cordless opener lasted a long time. “Another” purchase didn’t know he needed. So when the older one pooped out, I got right on line to get another. Great for our use.

      Best electric corkscrew - by far
      I have tried others but this electric corkscrew outshines them all....so far. Really like it. I have been disappointed with some before though if you get a very dry cork that splinters.....but this one has a much smoother operation and just works better. Good price too.
