Q: I love this collar! Very stylish and I like that it's easy to adjust the length. It's soft too so I feel like it's not irritating to kitty. I'd definitely buy another!

A: positive
****
Q: Definitely not worth the money. They overheat and burn my ears very quickly after being turned on, the battery life isn’t more than 30 minutes, when trying to watch a show or video the audio is very behind and they have this constant beeping/buzzing noise while they’re on that you can still hear over your music.

A: negative

Q: I Love This Diffuser! I have had my first one about 6 months and it has not skipped a beat! It is a great product for the price and the size is perfect. The changing lights are cool and pretty. I gave them as gifts,and everyone loves them! Just bought more for every room in the house. I would highly recommend this diffuser to anyone.
