Fails at some functions and greatly excels at others [SEP] They sell this as having a ton of functions, the Swiss tool of the shaver world even. It does have a lot of attachments and they are all pretty good quality, but the shavers are bad. The beard and head shaver don’t have the gear reduction to move fast and hard enough to have a smooth shave. The rest however are fantastic. I especially love the cleanser brush. It feel fantastic on my head after a fresh shave.
