Example Input: I purchased this one after I found out the 2 others I purchased from an on-line pet store were going to take 3-4 weeks to get to me. With a new puppy I needed one asap. So I purchased this one. What a disappointment! The "mesh" net was thin and easily ripped by puppy claws. There were NO directions with how to place it. The wall mounts were weak and fell off after one day. I was so upset thinking that the other 2 were going to be the same way and couldn't imagine why this net was highly rated. WELL when the other 2 came they were of much better quality. The mesh net was strong and solid, the wall attachments were big and once I stuck them on the wall there was no getting them off! There was a nice 1 page explanation of how to place the wall attachments to assure the gate worked best. WHAT a difference! The puppy has pawed at it several times and has not ripped it nor has the pressure he placed on the mesh torn the wall attachments off the wall - BOTH of which happened with this cheap version. Buyer BEWARE!
Example Output: negative

Example Input: I considered many options before ordering this headlamp. This was one of the least expensive options, but I love everything about it. The band is comfortable. The light is very bright and has different brightness options and you can adjust to shine straight ahead or down at your feet (and the adjustment mechanism is very sturdy and stable). I actually ordered a second one to keep by the bed for reading. At this price, why not?
Example Output:
positive
