Haven't used it yet but it's cool too I guess.
My dad often has to bring food from the kitchen he is doing work at or from his culinary school, to his room, so access to a straw and a straw cleaner is super helpful in that for him
Love to use it as it can be packed away into a short straw that I can put in my outlery full set.
A good quality product
I wish I bought 2 lol.
On a serious note though, the straw brush could probably be tweaked a bit to make able to go through the straw more efficiently. Maybe for the straw brush, use a twisting locking mechanism instead so that it does not get pushed back into its telescopic slot when cleaning the straw.
