Inexpensive upgrade that maximizes the performance of the marker. Just played in a tournament this past weekend and the refs thought that I had my marker in full-auto! I had lots of comments that my marker was "a friggen machine gun!". Great product for back players to dump a constant stream of paint and get those early eliminations. Also works well for those forward and mid players that can lay their own stream of paint as they walk to their next bunker.
It drains your hopper faster than anything else I have ever seen. Every fifteen seconds I'd have to refill my hopper nad I don't carry enough paint to sustain a rate of fire like that. Make the marker hungry for more paint.
If you're looking for something that is going to make your gun shoot faster, and can afford the paint bill to go with it then I would highly recommend getting this board. Even if you don't shoot that much paint, it is always nice to be able to get more shots off when you are snap shooting.
