It was spilled all over inside the envelop when it was delivered, no safety seal. When I tried to request a refund, it said not eligible for refund, contacted seller and sent picture, no further response. Posted review twice but nothing showed up, what is going on?!

Ex Output:
negative

Ex Input:
After just a few months of night time charging, the Apple watch won't charge. Maybe if the seller sends me a new one for free I'll write a better review.

Ex Output:
negative

Ex Input:
My son loves this. Did not read fully because I did not know it was a bouncer so it moves as they move. I think it has stoppers so you could prevent that if you wanted. But my son is a bouncer so he has learned to love it

Ex Output:
positive
