Received opener and charged it over night as per instructions that came with unit. It took exactly 12 hours for red charging light to turn to green. We then used it on our first bottle of wine and were quite surprised. Initially I held the opener with my right hand and placed it over the top of the bottle after foil had been removed. I activated the down feed button holding bottle by neck, however torque of device was stronger that I anticipated and bottle spun in my hand as corkscrew engaged cork. I literally had to grip bottle neck very tightly to overcome the torque of opener to remove corkscrew which came out very quickly. After cork was removed from bottle I applied pressure to release button on opener and as quickly as cork was removed it was ejected from opener.

Pros: Appears to be well made, very quick in removing and ejecting cork, would highly recommend to friends.
Cons: Color choices could be an option, other than that I have no issues with this product.
