Not water tight...? moisture inside lenses after only a couple weeks of installed use. Was sent replacement, and it did the same after only a couple weeks. Then after about 4 months half of the lights stopped working.

Ex Output:
negative

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!

This is working really well with controlling my appetite! I don't feel ravenous as I have before taking these supplements. I will buy again until I get to my desired weight!
