Anyone used one of these before? http://www.militarymart.co.uk/prod6.asp?prod_id=8362&id=191&sub_cat=523&grpid=8362&msg=&offset= Used to have a mate who had one, but I spent more time taking the p1ss for how it looked than asking him how good it was, and now I've lost his number. So anyone know if its any good? And what are its bad points? Or any other suggestions for a similar price?
