There are exactly two drinks that I find require straws:
a) milkshakes (and especially thickshakes)
ii) bubble tea
Otherwise I hate using straws. This “cleverly named, cleverly engineered reusable drinking straw that folds down into a package small enough to use as a keyfob” would be useless for both drinks - you’d either have milk residue going funky, or the bubbles wouldn’t go through it.
Edit: there’s one other use case - those little bendy straws that come attached to cartons of juice. I’d prefer they weren’t there but there’s not much I can do about the straw existing other than not buy the juice carton, and drinking from those cartons without using a straw is … problematic.
