Query: Great, when it works....

We've bought two of these for my wife. When they work, they work well. The problem is that it's way too easy to break the seal inside the handle casing , which results in the handle popping out and acting broken. This happens regularly.FYI - how you fix it:1) Twist the blue ring to separate the handle assembly from the bottle and funnel.2) Turn the handle assembly upside down and find the small hole in the blue part3) Rotate the blue part until the hole lines up exactly in the center of the handle3) Separate the blue piece from the white and you can then see the clear silicon - you should also see that it no longer has a tight seal.4) Remove, wash, replace and reassemble - solves the suction problem until it happens again (and it will happen again, often).
