No, never tried the UWW+. It came down to the UWW+ or the IUDJ and I made a coin-flip decision to go with the latter. Being 100% satisfied with it, and with how Garry dealt with a weird problem that came up with my order, I'm gonna stick with it.
I certainly have no qualms about somebody thinking the Ultima UWW+ is all that! I really like some Ultima products and had I tried that instead I'd quite possibly be singing *its* praises and saying how it's the only Rinseless for me.
Wading through the comparisons between IUDJ and UWW+ gave me the impression they're both great and that nobody'd go wrong with either.
