I like the P4 wrist flick activation also and find it to be actually practical as well as just plain fun.
I recently got a nice Gilette Reflex, which uses a similar but different activation system. When a Pulsar P4 owner first holds a Reflex, the compulsion is to start waving it around and "flicking" it back and forth, which does absolutely nothing. To get the Reflex to display, you need to turn it to a 30-45 degree angle with respect to the ground and hold it there for about one second. After you get used to it, it works well.
I find the wrist "flick" of the P4 slightly more satisfying / fun. However, it's a bit prone to inadvertant activation and I have to admit that the Reflex is perhaps slightly less prone to that. Also, the wrist turn is more inconspicuous and natural than the wrist flick.
So, for those of you who have tried both, which do you prefer: the wrist "flick" P4 or the wrist turn Reflex?
