The brakes feel somewhat plastic/less sturdy, but are performing well. Really like them for indoor low bookshelf.

Wheel roll desk is sturdy, easy to maneuver and locks work excellent. They make rolling my fully-loaded desk -- which is pretty heavy -- around very easy on hardwood and still quite easy on my low-pile carpet. Easy to lock as well.

These are 8m and around an inch in stem size. Perfect fit to replace the floor leveler. Double-check the metrics of the foto screws (if available) on your desk. They fit nearly all sit stand desks that are m8 threaded.

These wheels are really strong and sturdy for my standup desk. M8 threads work on ikea skarsta desk. The length & diameter of the screws on these wheels match up perfectly for size with the threading under my flexispot adjustable desk.

These casters fit my jarvis standing desk legs perfectly. Bought for sit/stand desk from amazon. Into my sandodesk stand up desk. Imam using it on a rolling stand up computer desk.
