The weapon is plagued with a couple of basic problems.
First, the suction cup used to attach the weapon to things does not stick to anything. If
you somehow get the suction cup to stick, the chances of the gun being lined up to hit the
enemy are next to nothing. Finally, if the weapon sticks to the fixed object and is lined
up (by some miracle) you probably wont hit anything because of the gun's weak range.
Save your money and buy something else unless you really want a
weapon that could attach to something.
