Its definitely worth buying; there are some songs on here that youre not going to get in better quality than this, at least until a standalone "Pulse" BD release, and in some cases ever. I?ve carried a quartered elk in another one. It has great loft, good quality, but it squishes out during the night so that you end up on a flat surface (see my review on it). Im a "weighty" guy, so I was pleased with how comfortable they were. I suspect that as the slippers get worn, they will loosen and coming down the stairs might be something Ill need to take particular care with, hence the suggestion to go down a size. Does not actually come with a Metal Carabiner as stated in the description I love the sound of this speaker, but I dont like being lied to. But they seem about 1/2 to 1 size too small. Lifetime customer, for sure! I went on the Havaianas website and grabbed a snap of their kids size chart for reference.
