The way it is described in the catalogs and on the box and the way it is packed, you would think you would need to keep small children and animals out of its way, but that is definitely not the case. The other reviewer said that it was worthless when it is clogged. Well, if that is case, it sure doesn't take much to clog it. I used it on one not particularly crumby keyboard and I literally could not tell if it had ANY (I mean ANY) suction. You would get more suction putting a straw to your mouth and sucking.
