A while ago we were sent a couple of Joystick-IT "thumb sticks" from ThinkGeek (note: ThinkGeek uses all caps for the product name -- I respectfully decline to shout at readers throughout this post, and I consider this an increasingly annoying practice by marketers). Designed to give an old analog joystick feel to your iPad, the Joystick-IT sticks are little metal joysticks with conductive pads on the bottom coupled with a suction cup so that they can stick to your iPad, provide some "bounce" (with the conductive sponge) and control a game by using your fingers or thumbs. Read on for a quick review of how these work in real life and whether they are worth the US$24.99 price ($39.99 if you buy two at once).
Well, I have to say these are cleverly designed. As you can see in the gallery, they provide a bit of spring from the spongy parts, and under the spongy parts is a conductive mesh to relay your controls to the screen. The metal on the sticks (necessary for these to work) feels solid and sturdy, not like a cheap plastic toy. The suction cup is necessary for sticking the thing onto the screen of your iPad, and comes off easily but not so easily it'll pop off during gameplay.
Still, the suction cups look like they'll eventually snap off as they are connected by a very small diameter of rubber to the stick itself. By "snap off" I mean they look like they'll break. They definitely popped off the screen without too much pressure. Plus, while the metal is necessary, I am a little concerned about damaging my screen should I push down too hard.
