I purchased this product nearly six months ago and it still works great. I open wine almost nightly (no judgement) and while it sounds like it is struggling a bit to pull the cork it is very efficient. I've only had to recharge it after about 40 bottles. The only negative is, six moths ago I bought it for $19.99 and now it's $29.99, a 53% increase in six months!!

Simple and effective

Works great- I've had three different types of wine bottle openers this is the best! Easy to use and has a nice cradle for keeping it charged.
