text: I have the 24 Oz Hydro flask and like many other customers was dissatisfied with the straw top lid that Hydro flask comes equipped with. After one wash it started squeaking. My sister had success with this replacement product so I ordered two with high hopes. But it DOES NOT thread correctly. Please see the photos. The threads are completely different from the Hydro Flask threads, so even my bulky hubby couldn’t muscle it on. Absolute and utter frustration. You don’t want putting your water bottle together to be the work out for your day. Don’t buy. Not for the 24oz anyway
