Works great, rolls well on carpet and LVP. No flex the frame.
Heavy duty casters. Great kit. Works as advertised. However there are two caveats that in no way take away from the functionality of the product. That being, you will need an ultra thin wrench to hold the spindle while installing. I paired mine with the Rigmetal basic. I initially installed them with the casters facing outside of the frame. At the rear of the rig I noticed the extrusion was bending outward under the weight of my seat and myself. I rotated the brackets to face inward and everything is perfect now.
These things are super heavy duty, easy to put on, and work great. Lifts up the rig to be able to utilize a monitor at desk height like the feet would but allows me to wheel it out of the way so I can use the monitors for other things too. Even better than I was expecting.

Well built and easy to install
