It is definitely a unique design. Unfortunately, it does not function well. You have to be very precise with your touch and you don't really feel the brush on my teeth at all. Not sure how else I can complain about something when it's still working perfectly after several months. One of the things that makes this toothbrush stand out is that there is no battery. With other batteries, they inevitably fail or die because they're always sitting around. This one doesn't.
Bad review

A nice case, well made from good material, fit perfect first day.
Bad review

I like these for keeping my feet warm on long hikes in cold weather. They are made of a soft but sturdy canvas and not as cheap feeling as some other boots. The downsides are: 1. When out hiking, they're constantly snagging small sticks when they don't need to; 2. They're bulkier than it seems from the picture -- making them stick off your leg all day. I'd say that this shoe is mostly designed to keep you toasty warm.

Good Review
