Product review (1 stars): AVOID. GARBAGE!
Do not buy this. Use the other kit mentioned in the comments. This is the exact piece that gums up and causes water leakage and ice on the floor of your freezer. Replacing it is meaningless as it is an inherently flawed design and your problem will simply return again when your new one gums up. The idea that they want 17 dollars for this thing is laughable. Absolute garbage. AVOID!
