[Q]: Useless, basically its like a kazoo for your nose, does not alleviate snoring at all, if anything it made by nose feel sore the morning after, and is easily clogged if you have sinus issues.
[A]: negative

[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!
[A]: positive

[Q]: The shell is flimsy and brittle with flaps that don't sit flat and a shape that doesn't sit square. The design relies on single snap-button connections on each side and pop-out hangers for the fabric liner. To much glare for what I needed.
[A]:
negative
