using a Kngertech Kbox and i have to say i really do like it. the form factor / grip effect is just right for me . i use a lot of setups that work well at 8 watts so i dont mind the fact it doesnt tweak to smaller increments and the under 20 dollar shipped to my door in three days was the real clincher . i would like to get a silicone case or something for it though . i just got a silicone case for the istick 50 and i really like that feel .
