As you know we are a new and used car dealer. I want to congradulate you on a very useful product. We get dozens of sales people trying to sell us some gadget or another, but this is the first one in a long time that actually does what it claims to do. John's training was top notch, he not only taught us the PSR system he showed us things about detailing that we have never seen before, but now saves us 2 hours on every detail. Amazing stuff, keep up the good work.
