I went back to the allergy medicine I was taking before. This did not help at all. I took it for a week, then gave it to my husband. He was unimpressed, said the generics we usually take work best for him, too. Very disappointing.

Ex Output:
negative


Ex Input:
I received way more tops than bottles--some that made no sense, AND NO TOPS for the smallest bottles. It was kind of a disaster. I would not recommend ordering this product.

Ex Output:
negative


Ex Input:
Love the strength of the magnets and the pencil holder. Great product I would recommend this case to anyone who wants to protect their iPad and travel with ease.

Ex Output:

positive
