“The straw is excellent but needs to be expanded by using the cleaning device before it "reinflates" after packing to enable sucking fluid. Otherwise it was blocked. The only other thing that bothers me is that the telescopic cleaning device would collapse when I inserted it into the straw and no matter how hard I tried, I couldn't get it to the center of the straw to clean it. This is going to be a big problem when I drink milky drinks! Other than that, easy to use, nice to look at.”
