ionics zero system.... now yer talking can I have 2 please 
hmmmm....spend 20 squid or 14 grand to try if it cleans any better. Wonder which one I should go for 
"For all those sceptics out there who have not tried it yet but still comment on the product best you try it first then if you think it don't work then say so but don't comment just to slag it off if you have never tried it."
Does that mean ive got to buy an ionics zero system before i can form the opinion that its for mugs who havnt done their homework?
Get a grip mate and get the point he trying to make which has nothing to do with either product. 
If you want something you will buy it if you don't you will not. It's as simple as that really 
You can do all the background research and read all the reviews if you like but that is just people’s opinions or what some call educated guessing if they have never tried it themselves. That goes for any type of product be it a 5p tin of beans to the most expensive motor on the planet. The price of a product don't mean jack poope really either as long as you can afford to buy it in the first place then all what matters if you are happy with the product or not.
It's a bit like the discussion going on about using hot water or not. Some will say they never need it and other will say it makes their job easier. Who is right it don't matter in the slightest if you ask me as is down to the individual what they decide to use 
No its not, the Ionics system is a good example of this, if you know how purified water works then you will know that filtering the water to a higher level isn't going to make any difference to its cleaning ability.
If you don't know how purified water works then you might fall for the Ionics gimmick its the same with everything
including additives.
I don't need to be a chemist to know that diluting any product to the level that Vision is diluted will render it useless
common sense and experience with stronger cleaning chemicals tell me this.
If this actually improved the cleaning power of water at that dilution ratio think what it would do undiluted.
