Query: Disappointing

I bought this shaver for my boyfriend who never had an electric shaver before. The idea of getting the electric shaver was to shorten the shaving time but this one made it dramatically longer. The first shave took over 30 minutes. I thought maybe he was doing it wrong but his father even coached him and he did everything the package said but it didn't get much better. The package does say that it will get faster in time but it hasn't gotten to the 3-5 minute shave my dad and sister's boyfriend has. It now takes him 10-15 minutes to shave with this razor and he still has to use non electrical razors to get everything. He gets a sort of razor rash with it too. He does have thick hair and sensitive skin so that may have to do with it. So yeah, if you are like him, don't but this shaver...It may work for those with thick skin and thin hair, that's the only reason why I didn't give it one star.
