Review on Instantly Release Steam Safely With The Silicone Diverter Accessory For Instant Pot And Other Cookers by Sam Bauer

This accessory says it works on the Duo. Turns out it's intended only for the Duo steam release knobs that have that pointy part, but it's not intended for the round steam release knobs. My new Duo has the round knob. I tried this today with a quick release, and it wobbled a bit for a couple seconds but stayed on and redirected the steam as intended. I held my hand in a long potholder an inch above it at first, just in case the thing came flying up off the knob with the steam. Other than the wobble, it stayed fine. I'll probably hold above it the first couple seconds for every use, just in case, but it's a really useful accessory.
