Dell's rubber feet keep falling off.

I have 2 Dell insiron laptops, one is an Inspiron 15 5515 and the other is an Inspiron 14 7415 2 in 1. Both of these laptops rubber feet have fallen off after less than a year. Keep seeing post after post of other people's Dell laptop feet also falling off. I dont know why Dell doesnt fix this issue with future models or use stronger glue. Some people got replacements after contacting customer support so I also gave it a try but the technition refused me because it "wasn't covered in my basic warrenty". And I can't buy replacements for the rubber feet because Dell only sells the entire bottom panel, which is quite expensive. After talking to him and showing other posts, he said he can't do anything and that I have to buy a replacement. Kept asking him for a price or a solution but he kept quite and just repated the same thing, "its not covered".

Does anybody know where I can find these thin rubber feet replacements for cheap? Next time I'll add super glue.
