As another reviewer noted, those rubber feet probably won't stick to the bottom of the laptop so it's a shame that they have them are sold like suckers. I still find them useful as an alternative to add some airflow without buying a fan. I only used the packing tape as I wanted to take it off to use on my lap or to carry to work.
