This is one of those items that you will wonder how you did without after installing.  The installation was easy and for those of us with glass lid covers that never really had a good place for them, this is excellent.  The tray rolls in and out very easily, it hold a good number of lids and is lightweight but sturdy enough to do the job.  It's one of those things you might just walk by in a housewares store but trust me, you really shouldn't.  This is terrific purchase.
