The problem is, the damn thing is a lot more trouble than it's worth. There's this plastic blue sheet of caps that snap onto the bottom of the tubes, so you can pull it off and push the ice out from the bottom end. But the thing is an absolute PAIN to get off! It hurt my fingers! Then you have to run the whole thing under warm water to loosen the ice enough to get it out, then you dump the ice into a plastic bag. If you can do this without losing any ice into the sink, bravo.
Then, after running the thing under warm water, the ice that comes out is half-melted, so you can't even use it for about three hours.
I'm about to go out and run some errands, so I got Mom to help me get the ice out. We went through the ordeal described above. Then I put some of the half-melted tubes in this Deja Blue bottle I've got, because I can't wait three freakin' hours to go run my errands! The ice is melted already, and I'm about to hit the town toting a bottle of lukewarm tap water. I might as well not have bothered!
