Like others said, the curled hose is a problem. The other is the stiffness of the bulb. It's hard rubber so it's very hard to squeeze the bulb to start siphoning. If the air temp is 65 degrees fahrenheit or colder, good luck trying to squeeze the bulb. I would've given this no stars if it was possible.
