Octa WhaleTail and Vacuum Dock is a tablet holder that suctions to the back and contours the hand very nicely. To get the back to stick on the iPad all you have to do is put it on there, give it a few pumps and it's on there, and rather firmly. Releasing the holder is pretty simple (once you get the hang of it) -- pull up slightly on the two tabs and then push them in, and off it comes. Also included is the WhaleTail which hooks onto the back of the Vacuum Dock which allows the tablet to be propped up and it also doubles as a security measure for when you are carrying your tablet around so it doesn't just fall right out of your hands.
