This product is very substantial, the thickness of the panels makes it feel very sturdy.  The white surfaces are smooth and look like they will last a long time.  It does take a bit to get it all put together but study the instructions a bit before you get started.  There are just pictures not written instructions.  It me about 2 hours alone to get this put together but it was pretty simple just laying it on the floor and adding supports and shelves a layer at a time.  I had problems with just one joint so I used a soft mallet to get the joint to fit well.  With all the bolts and connectors I thought it went together well.  With the 5 shelf unit it feels lie it could be top heave so be sure to anchor it to the wall behind it.  Excited to get my wife's sewing material folded and stored on the shelf so she has easy access to the material she has.
