It is very gentlemanly to the skin, very smooth, easy to take care of, will not hurt or cut your skin, the box is very good. Carry your bag and cleaning brush with you. The shaver itself looks and feels very good. It is light, easy to use, quiet and easy to hold in your hand. It is sharp and fast, and it shaves well. You can even shave in the shower because it is completely waterproof.

Ex Output:
positive

Ex Input:
Bought this after reading good reviews. But it's not water proof at all. If my son has even a little accident in bed, it goes straight to mattress. I don't see a point in having this. So I have to purchase another one.

Ex Output:
negative

Ex Input:
I got wrong color. I was looking for auburn but my color is almost black. I used this henna. I added tea and lemon to the mixture and hold it for 4 hours. My hair is almost black and not auburn as advertised. My natural color is brown. Not sure if it advertised correctly.

Ex Output:
negative
