Not only is the Fun Factory Laya Spot ergonomical, but it also comes in a variety of fun colors. It just fits into the palm of your hand, but gives off strong vibrations. It is unbelievably easy to operate, with one button for to turn it on and up and one button to turn it off and down. The LayaSpot comes in black/silver, silver/red, and magenta/turquoise. It measures about 6" and is very discreet.
