Product review (1 stars): Absolutely worthless. Worse than what we're replacing due to ripples.
As I type this, my husband's cursing in the kitchen about this door gasket being a p.i.t.a. to put on because of the bends & folds due to shipping. As you can see in my photos, the included instructions clearly say, "DO NOT FOLD, BEND, OR KINK REPAIR GASKET", yet that's how ours arrived. We have absolutely no suction for our freezer now, so it's worse than the gasket we were replacing, which was a stronger, thicker rubber & this replacement one feels cheap & thin in comparison. We seem to have wasted $109 because there's no suction for our freezer door now.

I suspect this is a cheap knock-off & not a Whirlpool product. The lack of branding on the included instructions seems to confirm this. I'm planning to contact Whirlpool corporate today to report this seller. I'll come back to update if there's anything new to report.
