Terrific design in principle, but not well made.
Unfortunately, I can only rate this product for two stars, due only to a production quality issue.  First, let me say that this lift is an outstanding design in principle - very comfortable, and accurately portrayed for what it does (adding perceived height).  However, I was only able to use them three times, at which point, the material covering the top began to peel off, and these suddenly became uncomfortable - and then unusable.  Evidently, the top material is only glued on.  So for the price, being able to use them only twice was just not worth the price.<br /><br />If these lasted (much) longer, I would rate them at least four stars very easily.
Rating: 2 stars
