I waited last month for it to cool but have since decided that it's probably for clinical situations where the urine is kept refrigerated?
That was my logic - have been using it fresh (

) this month and it's been fine as far as I can tell.
If you want it to cool quicker you can always fill the sink with cold water and put your cup in there for a few minutes.
Don't you just want to try one out? Just for fun? (practicing POAS pushing for future use

).
