I used electric openers previously, but this one is very cute and it’s all you need. It runs on 4  batteries, you don’t need to worrying about charging it or take charger when you are traveling. Foil cutter also attached to the unit, so you don’t misplace it or forget to carry it. Just one button, press the bottom side of the button to remove cork, it automatically stops when cork has been removed. Press the top side of the button to remove the cork from the opener. It also comes with a wine pourer and a vacuum stopper to close your wine if you don’t finish it at once. Absolutely the best!
