I have ALS and I love this it makes drinking a lot easier because I don't have to stuff so hard.
A stainless steel one-way valve solution that's easy to take apart for cleaning|||ARK's Premium One-Way Valve makes drinking easier by controlling the direction of fluid - fluid flows up into the straw, but does not empty back into the cup. Because fluid always stays at the top of the straw, less effort is required for each sip and less air is ingested. As a result, users tend to experience less coughing while consuming more fluids. The valve is easy to take apart, clean, and put back together. Highly recommended for individuals with oral motor difficulties, a weak suck, or problems generating and maintaining suction.
Caution: contains small parts that may pose a choking hazard; please supervise at all times.
