Yes we have tried, bought one as the v3 works well for us and more absorbency is always good.
They stain every time, think some fabrics stain more then others but well that's just the inside you don't see that.
Fit is the same as the v3, so if the v3 fits well this will be ok too. What I like is the extra booster you get with this version. Oh and yes they take longer to dry but heho the v3 dries very very very quick.
