I bought this product thinking me the job of uncorking bottles, painful for me who suffers from arthritis in the hands. Unfortunately, the system of "grip" around the mouth of the bottle opener is insufficient to prevent it from turning around the neck, forcing firmly maintain both the device and the bottle. Also the attack of the cap is not quite frank, which has the effect of "nibbling" inside the cap, if it is old or slightly porous. It is then removed by more traditional means. It is not a tool for its use.
