This works GREAT! I wasn't sure if this would be hard to set up and charge but it was SO simple. I just took it out of the box, plugged in the dock, and put the opener on the dock to charge. THAT'S IT! I love that it features a red light to show that it is charging! So many times I have left electronics because I thought they were charging only to come back and they have no juice! This takes out all the guesswork. I look forward to many more open wine bottles in the future because of this beauty. So glad I bought it!
