Worse than nothing at all
This is an awful product. It is actually worse than letting your crust go naked. When I used this so-called "protector", the edge got brown to the point of burned and it crushed the edging crimping, presumably when the dough warmed in the oven and gave way a bit to the weight of the "protector." Over the years I've baked tons of pies with homemade butter & shortening crusts. I usually make a homemade edge protector out of aluminum foil that I leave on until the last 10 minutes of baking, although occasionally I get lazy or in a hurry and don't do this, so I'm well-familiar with how the edge of the crust looks with foil (no browning at all) and nothing (some browning but not close to burned). Save your $6 for 3 Lotto tickets. Or literally anything else you can think of.
