Product review (5 stars): Might need it...but glue works for now.
When our actuator snapped into two pieces last week, I found this to be the most reasonably-priced replacement on the web. BUT, since it still means spending $70, I held off and went to Home Depot and spent 20 minutes comparing different plastic-fusing glues. I went with Henkel 681925 Loctite 0.07-Ounce Super Glue Plastic Bonder, which is also sold here on amazon.com

Following the instructions (applying the primer on both surfaces, waiting for 60 seconds and then applying the glue sparingly on one of the two surfaces you want fused together), I added another thin bead of glue to the joint then carefully held the two pieces together with blue masking tape. I left the tape on for about 24 hours, and it's been five days since and the glued together pieces are staying put. Feels like it never broke.  Of course, our house has no kids--just my husband and I so we don't really slam the glass against the lever, which is something kids could easily do.

Note: I left the the actuator on the freezer door which means I did not need to use any tools (it broke where the top of the clear and black lever tapers off suddenly narrows but thickens towards the top).
