[EX Q]: Love this pet feeder! It has automatic feedings so I don’t have to worry about feeding my dog anymore. The camera and microphone quality are very good! I love the fact that I can check up on her when I’m not home.
[EX A]: positive

[EX Q]: Bought for preteen daughter. Easy to use. We put curl cream in hair while wet, then put these in her hair and kept them in over night. Curls looked great. No tangles when removing. Great quality for price. Delivered quick.
[EX A]: positive

[EX Q]: Although I haven't been able to actually use this product yet because my new computer systems haven't came in yet. These do look stunning and the headphones feel great on the ears.
[EX A]:
positive
