I used them for my daughter's wedding and then for a large family reunion. Really nice units, good people to work with. They gave me a day & time for delivery, where the others I called just said "Sometime Friday," so I'd have been stuck all day. White's gave me a 1-hr block of time, called when they were leaving their yard, and delivered right on time. Best service I've ever had from a toilet company, bar none. Another thing I liked was that the driver was careful, pleasant and helped us pick the best spot for the toilet, reminding us that shade was important for the comfort of the guests, etc, and figuring out where to get the best afternoon shade in the yard. Nice family business. I'd never use anyone else.
