I have tried their citrus Power and whilst it works well, the price point over here in South Africa means it works out to be around double the cost of Valet Pro Citrus Pre-wash which I find works equally as well.
I didn't particularly like their Lather shampoo or tire dressings (gloss or satin)
Iron Out tends to dry out much quicker than my go-to iron remover from Valet Pro (Dragon's breath). I have also tested it against Carchem Revolt and prefer that over Iron Out too. Iron-x of course seems to remain the yardstick in terms of performance, but again pricing over hear makes it hard to reach for on an ongoing basis.
I haven't used any of their waxes, but then I am one of those guys that isn't really *into* lsp's (especially the 'boutique' type stuff)..... something like Collinite 915 is for me, all the 'show wax' I need. Collinite 845, Menzerna Powerlock and Optimum Optiseal are others that I use often.
What I really do like of theirs though is Dressel, which is literally a spray and walk away type dressing I like on engine bays, along with Spritz which is an 'interior detailer' that has a really nice smell, supposedly some decent UV blocking capabilities and leaves a nice, non-greasy, OEM look
