These slides are beasts! I mean, for example, Arnold Schwarzeslide! It's like the Hulk and Chuck Norris got together and decided to make drawers. Yes exactly. The only downside I can say about them, and it's a very small downside, is that they're a bit difficult to install. I actually built a plywood clip to hold the drawer in place to align it. They do not separate from each other so once attached you will need to remove the mounting screws to take the drawer out. Otherwise great product! They're cheaper than most comparable slides I've seen. Just a note, mounting screws are not included. In general I am very satisfied. A total of five stars plus.
