We had 6 cabinets done by Roll Outs Quick. 2 Single wides and 2 double wide, a total of twelve cabinet shelves.
Quick it was. Very pleased with the work. Measurement took about an hour, three business days for fabrication and literally less than an hour for install with the auto-soft close hardware. Each shelf is fitted to maximize the space while clearing the door and power and gas hardware for the range top.
Since the install, I've been absolutely stunned by how much more convenient they make the lower cabinets. We have our gas range top set into the counter top with a double cabinet below. All the pans are there. Now it's just open the door, pull the shelf out and look down at every pan we have and easily pick it and the cover out, no hassle, no kneeling, no bagging pans around.
Pricing was great too, IMHO, basically, $10 more per shelf to customize and install over ill fitting big box store product.
Also was very pleased in that they worked directly with my wife and provided her with a straight forward and honest quote and good feedback on maximizing the shelving for the cost with the doubles. They didn't try to gouge or blow smoke on her.
