The biggest problem I've had with 2-in-1 models is the quality of the pen. While it's certainly nice to have a writing implement on the other end of a stylus, on most of the models I've tested, the pen is a rather cheap-feeling ballpoint--not exactly what you want to use on an important document. The Flip eschews this trend, and wonderfully so. Its pen tip is silky-smooth on almost any surface, and it's a pleasure to work with. Adonit also wins style points for the way the company has incorporated the ballpoint: Just twist the end opposite the stylus, and the pen rises out like a snake called by a charmer. Once you're finished, wind it back down, and the Flip looks like any other Jot.
One note: If you do a lot of writing with the pen, the Jot Flip's tip may require more-frequent cleaning than your average ballpoint. I found that ink would occasionally crust up around the tip, making it difficult to write unless I wiped it clean with a tissue.
The Flip's body is also an upgrade from that of the regular Jot and . Polished, silver-finish steel and a decent rubber grip give this stylus a more-balanced weight for both writing and drawing. A clipped, screw-on cap allows you to protect the disc end of the Jot when you're not using the stylus; this cap can also screw onto the pen end while you're using a touchscreen surface.
Thanks to that weight and balance, the Flip writes better on a touchscreen than either the Jot, the Jot Pro, or the . Unfortunately, problems I've had with the Jot line in the past--the lack of a spring tip for navigation, and the plastic disc's poor resistance on touchscreens--remain and prevent me from rating the Flip as highly as I'd otherwise like to.
If Adonit could make a few adjustments to the Jot line's stylus tip, the Jot Flip might become my favorite multifunction stylus. For now, it's a solid option for those who want to write on their touchscreen and on paper, though it doesn't match the best touchscreen styluses.
