[EX Q]: I was immediately disappointed with the quality of this ring. It bent as I was removing the tag. It's pretty and it hasn't turned my finger green YET, but overall disappointing.
[EX A]: negative

[EX Q]: Now we are living a bark free life! Within two days it had cut out 99% of non-essential barking! At last you can feel peace and quietness in our house! We love our beagles but they were driving us crazy! It really detects barking from far away, now we don't even hear our neighbor dogs. Great quality and cute btw...This has been a life saver! We are able to get proper sleep now!
[EX A]: positive

[EX Q]: I read all the reviews re: size of these slippers before making this purchase for my son who is a big Boo fan. But the sizing is still off. It was smaller than expected and because the head of the Boo is big, you have to be careful not to trip!
[EX A]:
negative
