Great product.... think hand masker and the difference it makes in your daily production. Simple to use. After about 3 doors you'll be up to speed with the Door Racks and the finish product is excellent. The reason for four stars, I would have preferred the racks to be a little heavier gauge and a little taller ( I'm 6'6") probably a little nitpicky. Bottom line, buy a set and compete or don't and I'll do the job!
