The trays slide around (to the back and/or front) too easy!  Total PAIN!  The actual item is the look I was going for and I was so excited to unbox it!  Nice looking on my desk and not the "typical" file system.  I will have to do a "DIY" project to get the shelves to stay put but still be able to slide in and out when necessary!  I actually purchased 2 of them because I like the look so much!
