* Does the bit driver is as robust as the philips screw in a ST, I plan to use it for heavy wood philips screws, perhaps using the
No. Infact if you're only going to use a philips, i would advise you look at something with a dedicated driver. If you want the versatility of using other drivers, than the bitdriver is a good compromise. Get the shaft extender and it'll be almost as good as a dedicated philips driver(though you still wont be able to put as much torque into it)
* Are scissors usefull and suitable, or that's a gadget (Using on thin plastic, paper, nails, .. )
Paper and plastic? fine. Thicker fabrics? Sure. Nails? Nope, but thats what the hard-wire cutters on the pliers are for.
I personally think the scissors on the PST2 or original wave are better, but the ones on the wave, charge, blast and fuse are still totally useful and worth having around.
* Is the pocket clip secure in your opinion ? (for loosing the great stuff)
Should work fine. Its not as tight as ones that screw into the frame like on the skeletool or freestyle. Just to be clear though, its an after-market item. It isnt included with the charge.
* Do you now a online shop in USA able to ship in Europe ( nope in HomeDepot as in amazon.com)
Try ebay. Odds are it'll be cheaper anyway.
