I need such small pads for small items like urc mx-3000 remote or skycrophd 5 port hdmi 2. Great adhesion. Does fall off a little but luckily there are a lot of them in the package.
The dots are very tiny which i had wanted for the item i needed it for. Not sticky enough to stay on my painted cabinets after only a couple days. Way too small except maybe for a doll house cabinet. Don't stick good at all.
The only thing i don't know is how long the felt bottoms will last. My hunch is that they'll last a long time. Much better than the 3m alternative that is priced much higher and doesn't even hold up a month.
The only con is that the screws are not very deep and it is hard to get the right philips driver to not strip out the head. The only thing is that you should drill a starter hole to protect the legs.
With jute rugs, the small felt pads get trapped in between the fibers. The issue is where the laminate floors meet the tile.
