## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    They DO adjust for different widths!
  

*by E***E on Reviewed in the United States on March 4, 2010*

The other reviewer must not have thought about how to adjust it where you want it, but they do adjust to whatever length you want - I use them for extra shoe shelves in a cabinet.  They will NOT hold a ton of plates or other heavy items, but I didn't expect them to with this design.  I am very pleased with these and ended up buying two more for more shelves.  To adjust to different widths: the "rester" shelf (the one with only legs on one side) is inserted (legs down) from underneath at the desired width on the "supporter" shelf, then you lift the "rester's" legs-side up to "rest" the shelf on the selected wire on the "supporter".  The previous reviewer must have thought you can only rest the "rester" shelf on the end wire of the "supporter", when in fact you can insert it from underneath wherever you want.

    Not as expected
  

*by A***N on Reviewed in the United States on February 24, 2010*

I bought these "extendable" racks because I wanted different rack lengths in various cupboards.  Turns out they are expandable to one size only.  It's either 16 inches or 32 inches, nothing in between.  To make it worse, they are NOT strong and durable as promised - the shelf sags under the weight of only a few plates, and drinking glasses balance on the shelves so precariously that I am too scared to use them for glasses.  Also when they arrived, each set of racks is secured with a plastic band.  In order to remove the band, one must jam the scissors in there and wiggle them around to get a good place to cut, yet doing so chips off the paint and rubber coating of the racks- terrible packaging design.  Don't buy these unless you want them to be 32 inches long.

### ⭐⭐ 







  
  
    Concept is great but they used a high gauge thin weak metal grid material to make it. It dips!
  

*by J***K on Reviewed in the United States on November 23, 2016*

It does dip down if expanded not completely but 80%! Which is should not do that. Very questionable the way it appears after expanding. I would only put non breakables onto this item.
