Have had several high quality brands of rechargeable wine openers over the years and finally got tired of having to throw out seemingly good openers just because the battery stopped charging. This opener has replaceable batteries so thought we would give it a try. Now that we have had it several months we are very happy with the results. Batter life is quite good. In fact we just replaced the no-name brands supplied with the opener because it was getting very slow. New batteries and all is good again. It has plenty of power and works great. I think we are going to enjoy this opener for a long time!
