@heavanet- I think that a magnetic door holder would help keep your front door on nice days, but you will want to make sure that you buy the right kind to maintain the looks of your entryway.
Some magnetic door holders are large and look very commercial or industrial. I don't think that these are good looks for a residential home.
The best kind of magnetic door holder for a house is the type that looks like a knob and can be placed close to the floor. These holders usually are small and stylish, and also come in a variety of finishes to match your current door hardware.
