Bought on sale and so glad I purchased.  I put this in a really tight location, so a little caution is required in pulling it out, but it has made life so much easier.  No more rummaging around blindly on the floor trying to retrieve items which slipped past my grasp.  Very well made, just don't expect to overload it with canned goods or heavy food processor equipment as it will tax the engineering and glide.  Very pleased with it overall; provides a lot more useful space in my small kitchen.
