Works very well with initiating suction by squeezing the blue bulb 4-6 times, then the water starts to flow down into my pail.
One minor issue with a few occasional small water droplets in the middle of the tubing — I can’t dry them despite hanging them straight, on the window in direct sunlight, for 5 days. I gave up and just kept the tube in the cupboard. But I assume the tubing will eventually dry by evaporation
