I use it too. I like the fact that my customers comment on the clean smell of it, besides the fact that it is a one size fits all product. I don't ever recall a customer mentioning the clean smell in all the years of cleaning prior to using O2. I suppose that's because most all mfg.s are scared of putting too much scent in their products, and so by the time you dilute them to the RTU diliution ratio, you can't smell them anymore.
I use Judson's 02 also, along with other products they produce.
The cleaning results are superior using Judson chemicals, as they are mixed more concentrated to go further, but more importantly, they produce amazing cleaning results for my customers!
