This is probably true for the original crown. I have the original and currently using the crown 2, but I'm unsure if the crown 3 has a longer pin than my 2. Can't try it myself until the 25th.I use a uWell Rafale on my RX200S all the time with NO Problems. I don't have a Crown but I don't think it is much different than my Rafale.
Good Luck
THIS! This was reassuring. Thanks man!I have used 20 different tanks on my RX200S without a problem at all.
