[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]: First of all, they took a long time to get to me. They come with no instructions. No way of knowing when they are fully charged. Charge doesn't last long, at all. And they scratch very easily. Very disappointed with this product unfortunately.
[A]: negative

[Q]: This grinder was amazing for the first two weeks. Then it encountered a bean that was a tad to tough and the handle snapped right off. I didn't realize how weak and poorly designed the handle was. Needless to say I'm extremely disappointed.
[A]:
negative
