Retractable Touch Screen Stylus with 3.5mm Earphone Jack Anti-Dust Kit for iPhone 2G/3G/3GS (Black)

Pros: It works, kind of. The small headphone jack is pretty helpful since I can attach a lot of other stuff like cellphone avatars and hooks and other stuff.

Cons: It doesn't work, kind of. You have to push a bit for it to register on the screen. The tip is made of rubber so it is not useful for sliding or dragging on phones. I tried it on my Motorola Droid and it was kind of a pain to use.

Other: It works for tapping and not for anything else.

Pros: Small, good plastic and the idea of connecting the stylus to headphones jack is cool in theory.

Cons: The stylus does not pick up touches unless you press the flat side of the rubber tip against the screen. The flat rubber tip covers too large of an area for drawing (the main reason for needing a stylus in the first place) or precision contact. The headphone connector broke, luckily not while it was plugged into my iphone. The rubber on the tip grips the screen too much making movement difficult, also leaving smudges on the screen wich are difficult to wipe from the screen.

Other: Its not useful, dont buy it.
