How to fix a drawer that doesn't slide properly

My drawer doesn't slide right on the dresser or chest of drawers. The plastic slide pieces are broken. The drawer slides all around when I go to open and close it. This repair is super quick and easy. It is also super cheap. I bought some new plastic pieces from Amazon and they fit right in. I had 4 drawers fixed in about 15 minutes
Here is a description of the kit that I bought from amazon
