I appreciate the thought, and that's a good feature in theory -- but they did not put it in practice very well

This pencil felt a little wobbly and did not see any difference from this product versus a regular cheap mechanical pencil that doesn't have the twisting features

Second best feature is the retracting tip

One nice feature is the metal tip is retractable

Love the rotating feature and resulting sharper lines

The best feature is the collapse metal sheath that goes back inside when you're done using it so it doesn't poke through your bag or pencil case

The only really good feature is the retracting tip which is not thin and doesn't get bent when dropped.

Don't overload the refill slot with too many leads as it will tend to clog the mechanism and won't uptake new sticks as needed

It is so easy to grip as well as to write with it
