i love the stuff now.i put a few squirts of it in my tank most days.i think im the only vision user who got a dispenser bottle that didnt break!mine still works fine 10 months on. 
ive still got a full "original vision" bottle left from the 3 bottles i bought ages ago and about a quarter of another bottle.i love the smell as well.is the new stuff odourless?
i really notice the difference if i dont use vision.the shine is just....well....too dull somehow just using pure on its own. 
There's very little odour or bubbles, but the after shine on windows and frames is still very apparent.
I actually find I put slightly more vision in my tank now, usually 7ml into 500 litres, as I'm more comfortable using it without all the bubbles.
Strange thing iv noticed since iv started using vision again the last couple of months...birds flying into customers windows!
Had 3 jobs just today with bird imprints on the glass.
Must be the shine..
