If your kids, like mine, drop and throw electronic devices, this is a lifesaver, useful to use, helps keep the screen off the ground, when it falls relatively distance with relative strength, it doesn't provide screen protection when it's on, but so far has saved my kids' tablet from accidents. Material is very similar to Crocs but less dense, can be machine washed or rubbed or hand washed. Being a little less dense than Croc's means it will start to wrinkle at the grip with use, but if it were a little denser and made of the same material it would make fitting the tablet more difficult, which is already causing some difficulties. The only downside is that plugging it into the power takes some fuss and hassle, but it's not a big deal if you don't have hand movement issues.
