Purchased as a Christmas Gift and was so happy that it was well received by my spouse. he loves it and it gives him a very close shave for an electric razor. Looking forward to his nice smooth skin. Thanks

positive

I like the color and material but that's about it. THIS WILL DO NOTHING TO PROTECT YOUR SCREEN OR CAMERA. My screen stuck out from the case, and my camera almost sticks outside the provided lip. It'd be worth spending a little bit more to protect your $1000 phone.

Ex Output:
negative

Ex Input:
I purchased 2 sets. I've used this cup only for a day, then I found there is water between two walls. There is no crack at all. How could it happened? Now I only can use 3 cups.

Ex Output:
negative
