I booked a chandler installation with them on Amazon. The site specifically says that the cost is an estimate, and that more cost may be incurred depending on the circumstances of installation, which I am totally cool with, and expect. I was never contacted by Dan Keen Services, and instead, after 2 weeks, they cancelled the order with the message "More work than scoped on website." These guys (or guy) wasted 2 weeks of my time and weren't even willing to call and discuss the installation.
