Excellent bluetooth connectivity and range and good battery life. The audio is better than I expected. Highly recommended for newbies who are trying trimmers for first time. The charging lights are brighter than they should be to the point that they?re distracting The shoes are at least a half size smaller than my normal size! Ended up giving the shoes away. When I was unplugging it, for no reason the audio jack thing that enters the hole snapped off. They explained that it would be about two weeks for delivery. It does an ok job.
