Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Output: Negative

New input case for you: I bought this bag holder to use in my yard to collect leaves anddog droppings. The construction is very flimsy and the little tabs that hold the bag in place are VERY VERY hard to get off!. After several months, it now can barely stand up by itself and I have to constantly tighten the wheels and other screws. It would be nice if it was better made and sturdier and if it had a cover to keep out the flies...It seemed like a great idea, but the products is not well made.
Output:
Negative
