Furniture Coasters,Piano Caster ... vs Glass Top Bumpers Anti Slip Pads...

The tops are nice and wide, so they should be usable for a lot of different things. I really like the low-profile design, the unobtrusive color, and they're large enough to accommodate a range of furniture leg diameters.

These coaster cups offer unbeatable protection against the dreaded slip-slide. The rubber coasters grip very well. They are handy for keeping furniture from scratching hardwood floors.

There is too much friction due to the casters being made out of soft rubber. They are extremely small and don’t hold a standard glass size within them.

Not flexible. It’s not an adhesive. No las recomiendo. Doesn't work, good idea, but doesn't stick.
