It does what it claims to do. I recommend placing some double sided 3m tape on the bottom of the file cabinet before placing it on so it doesn't fall off while your moving your file cabinet around.
Needed a way to easily move my heavy file cabinet and this file caddy works perfectly. And it is much less expensive than other offerings of similar products.
This took only a few minutes to assemble and was essentially self-explanatory. So far it rolls well across both carpet (without getting stuck) and wood flooring (without scratching). If you’re buying a filing cabinet this is one of the best ways to prevent the metal from staining carpet etc.I definitely would purchase this again.
