They absolutely do the job. They make chair movements quieter. Seem to conform to different style leg ends and stay on securely.

They grip nicely. Did exactly as advertised. These are really easy to install.

These aren't great for sofas or recliners. After much force is applied, the felt center of the sticker rips off.

Would absolutely not recommend purchasing these. They are completely ineffective because they deteriorate so quickly. They do nothing.
