I recommend the Schiktion hair removal device!

I've been using this since high school. You can use it without buying gel or foam separately, so you could call it an all-in-one product. It features a 3D head that moves along the curves of the surface, and I like that it lathers up really well. It has a safety net attached, so you can use it safely without any risk of injury. Usually, you are bound to get cut when using epilators, but I like that you don't have to worry about that with this one :)
