Product review (5 stars): Works! Just note the tip in install
Edited 8/28/26:
At first I was disappointed because I couldn't figured out how to insert this into the holes in my fridge. There is a trick provided by the seller (see the comments). You have to insert the legs on the LEFT hand side first, and wiggle it a bit until you find the deeper hole. I really appreciate the help!  I saw the other reviewer was bummed to not get the extra black plastic stopper (which comes as part of the existing freezer shelves) but actually, it doesn't seem like the shelf will easily fall based on normal usage because to get to the deeper holes, you have to lift up the shelf a bit and wiggle it.
