The Paintball Rocket is constructed to take the abuse of everyday use.
The rubber band that "springs" back the trap door.
Overall, I have been using the Paintball Rocket at our fields. (SplatBrothers PaintBall™) It is great since there is very little spillage of paint if you know how to use it. Our refs demonstrate to the players how to use it just once and they are ready to go. I feel that it is a customer service to provide the Paintball Rocket and the players appreciate the loss of less paint.
We have had several teams buy the product based on what they have seen in our staging area. They also love the speed with which they can load a pod.
If you want a safe way to load your paint, easy to use, and lightning fast then I would recommend the Paintball Rocket. The teams love it and so will you...
