I got the two P3D's and I must say that they are awesome. They exceeded all of my expectations.
They have no momentary on function but they click on very easily and they are as bright as heck. I blinded myself twice last night just from the reflection of the beam from my patio door. The rear switch only needs the lightest touch to switch to strobe mode too. More touch sensitive than it is an actual click.
I liked them so much I ordered another one of the P3D's (so I can have one in each vehicle) when I ordered the two TK10's.
