We have wooden shutter/blinds in many of our front windows. I recently replaced the magnets used in the shutters as over time they have cracked due to being in the sun. I purchased the new shutter magnets at "MyKnobs.com". They were delivered quickly, look nice and fit perfectly without requiring me to make any modifications. Only time will tell on how they can stand up to the heat and change in temperatures we have in Texas, but on-time delivery, fit, finish, per unit cost and looks I would not hesitate purchasing them again from MyKnobs.com.
