The caster wheels sit in the felt pads but not snug so when you move/roll the chairs they come right off. The caster wheel comes off when the chair is rolled.

Good glue that doesn't come off easily without a bit of prying but did come off cleanly. These little dots work perfectly! They are the correct size for my needs and they seem to stick quite nicely.

Having to constantly replace pads due to adhesive just not staying on and sliding off. Now doors stick even more because residual glue sticking to everything. These vary wildly.
