Example Input: These are by far the best quality and most durable dog toy I've found. I don't feel like they should be $25, but that's just me.
Example Output: Good Review

Example Input: Purchased this for a gift and my son loved it. Only complaint is that you have to put in the batteries but other than that, it works great right out of box. Great idea by KidDoh, we would definitely purchase again. Love these things! :)
Example Output: Good Review

Example Input: This has so many problems. the screen scratches super easily, I think its one of those plastic screens that gets scratched when you put something on it, but it was just like that. The back comes off..really easy and then it's not a good design. It had more problems than i can count after 3 days of owning it. So in conclusion. BUY A KINDLE FIRE WITH BETTER PRODUCT.
Example Output:
Bad review
