I've had mine for years and had to replace the mat even. I like that the angles are adjustable and correct. It only takes 1 pressure point to hold the ruler, which helps because of the pain in my hands from arthritis. Without it I wouldn't be sewing/quilting as much.
I store mine under the TV cabinet in my living room. I made a wrap with some black ripstop nylon from Joann's to keep the case cleaner and blend in with the furniture.
