not worth the time and money [SEP] the item is not worth getting the first shaves were okay but after that it takes foreverrrrrr to trim your head the angled foils seem like a perk but it really does not make everything easier or faster because in essence the unit is really just separating the foils from each other resulting in a slower shave my traditional foil shaver the ones with two sets of parallel foils actually trimmed my head faster but even then that took a long time i really only got this device because i wanted to avoid the bloody mess of shaving with a razorhere is the truth there is really no device that can provide short cuts or easier methods when it comes shaving your head bald nothing will ever beat the results of a traditional straight edge or double edge razor i would suggest investing some time to practice the art of shaving with a straight edge single edge or double edge razor over time you will actually learn techniques to shave your head fasteror you can buy this unit and spend more than an hour shaving your head lol
