The one-way valve actually works — nothing flows back into the bulb, which was my main worry. Took a minute to figure out the right angle, but once I did it was quick and comfortable. Compact enough to stash in a drawer without it being obvious.

The bulb holds way more water than I expected for something this compact, and the one-way valve really does keep everything flowing the right direction without any backwash. Cleaning up afterward is quick too since it all comes apart easily.

Wasn't expecting the one-way valve to make such a difference, but it means no messy backflow at all. The bulb is compact enough to stash in a drawer without it being obvious.
