Drink Caddy Golf Dispenser Oversized 440cc Driver Hot or Cold

The pump on this is very weak. I tested it out with water and it could barely pump the water up to the driver head. When I tried it out on the course, I had to squeeze the bottle in order for me to get anything out of it and then it leaked out the bottom. The driver head part of this is actually very high quality though. I will be reusing that part and building the rest of the system from scratch. When I'm done, this will work better than what they advertise.
