Product review (5 stars): PERFECT for fellow crushed ice lovers!
I rarely write reviews, but this is the best kitchen gadget I've gotten in a long time.  I love to chew on crushed ice all day - helps increase my water intake, and I've loved crushed ice since I was a kid.  The ice dispenser on our old fridge died, so I was searching for something to use until we get a new one.  Tripped over this, and read a lot of reviews, and was helped greatly by a few people who mentioned the consistency/texture of this ice.
Prior to this, the best ice I had ever come across to crunch on was the ice you get at the hospital (not familiar with the Sonic restaurant ice several people mentioned), but this is even better to me.  The cubes are essentially like little, hollow bullets.  I always pick the "small" size (can make either small or large ones) - I assume the large ones are just maybe thicker.  But the texture is almost like compressed shaved ice.  Perfect for ice chewers, as it still has the crunch, but is not hard on teeth or dental work at all.  It's a little harder when it first comes out (but even then I think it still wouldn't harm teeth), but as it sits for a few minutes, it becomes even more awesome.
It is super easy to use and makes ice pretty quickly, too.  I fill it up with approx. 9 cups of water in the morning, and then just add water periodically during the day.  It makes around 10 cubes each cycle, but it makes them every few minutes and they build up fast.  It is also very easy to clean/maintain.  At the end of the day, I just unplug it and drain any remaining water (there is a little plug on the bottom), dry out the inside with a towel and then leave the lid up overnight so it dries thoroughly.
I don't want to ever be without this!  Even once we get a new fridge, I will continue to use this for my ice. It is also so easily portable, you could take it or set it up anywhere - wouldn't have to be in the kitchen.  You could set it up on the porch in the summer, or take it in a camper or to a hotel or whatever.  I have already told several friends about this thing, and they have ordered them too!
