At least the adhesive backing is worthless on smooth surfaces.

Super easy to install, very sturdy,good for protecting the wood. Only had them for a few weeks but so far very impressed.

My chairs have square legs and i have hardwood floors. They slide effortlessly and very quiet. We have tile floors and i bought these to reduce the noise the kids make.

These are perfect. They fit on round, square and all sorts of weird shaped and sized chair legs. It is important to get size that fits snugly. Measure chair leg diameter to choose size.

These split on 1 3/4 chair legs within 2 weeks of installation. They honestly look like condoms on my stools. They tear and will probably get worse over time.

Would appreciate a refund for these defective items. Very disappointed. Would not recommend them.
