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 Output:
positive

Great book if you bought an air fryer and want some more recipes!I just tried a few recipes, but it's really a good starter book for learning the initial use of your fryer.

positive

Very easy to use. Loads both my single stack and double stack magazines. But this item keeps locking closed while trying to use it to load. Only have had it about 6 weeks.
