Tried it
Not totally proffessional looking but best pair of rosettas done by me to date. Still learning what's the best way to texturize the milk with this tip, I installed it only some days ago. The foam quality -taste wise- is gorgeous. Silky finer bubbles and much more durable.
Be aware that I installed the tip to my Izzo Duetto changing the steam wand for a LM FB-80 one, but I'm pretty sure that the same should work with the S1 because the Duetto stock steam wand is the same than the Chris Coffee sells as the no-burn steam wand - The Quickmill steam wand
(yes, I know, absolute coffee mess

)
