These are the worst for so many reasons!!! I purchased three of them and all three broke within 1-2 months. The internal mechanisms are made of VERY cheap plastic, each unit is broken in multiple places (I was able to fix some of the breaks with wood parts I made but I gave up as they kept breaking in other places). I wear a size 10.5 and the units will not close with my shoes inside (so o.k. for my wife and kids only). How stupid is that? Finally, the assembly instructions are awful.
