FOOTMASTER GD-60S-1/2 Nylon Wheel and NBR Pad Leveling Caster, 550 lbs, Stem Mounted with 0.5" Mounting Hole Diameter, Ivory Finish

These are sort of handy and somewhat low profile / sleek, but also sort of annoying. The little orange wheel to be painful to use due to its poor design. Enough that we dread the slow and painful process of setting it that we went back to locking casters on most of our equipment. For moving equipmement frequently, these are just too unpleasent to use. The ratcheting ones are far better in this regard. The biggest reason we tried several sets of these is the thought that they would be very solid, but to our disappointment they wobble only a bit less than locking casters.

While making the island some what easy to move, the single stud does not keep the wheel from tilting down, so I had to remove the brake pad off of all 7 wheels.
