Telescopic Stainless Steel Travel Straw with Carry Case and Cleaning Brush 3 "Good idea, but....." 23 December 2019 This great idea falls a little short when it comes to cleaning. The straw itself is a brilliant idea, but the cleaning brush keeps collapsing when trying to push it through the extended straw. I have to collapse the straw, section by section, to clean it. Even then the last narrow section is quite tricky as the brush only just reaches. Leaving it extended and using the dishwasher now.
