Question: This cookbook isn't simple, as claimed. I bought it for the photos and supposed ease of recipes, but the truth is most of the stuff in there is flavorless and more difficult than necessary. The most frustrating part, aside from it not being recipes most people really eat, is that the 'simple' recipes require having other recipes made before-hand, and then lists them as an ingredient. I sent it back.

Answer: negative

Question: 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!

Answer: positive

Question: It typically works for a few turns and then nothing comes out after that. I would shake it to try to get peppercorns to feed but that never really helped much. Only emptying it, clearing the neck and reloading it would get it working again for a few more turns. Seems like the neck is too narrow and gets clogged inside. I finally tossed it out because even the disposable McCormick pepper grinder works consistently without all the fuss.

Answer:
negative
