We bought two sets of these curtain rods to test them out in various locations of our apartment before committing to them as our "solution".  I am pleased to report that we now have a curtain in place to separate our closet from our only bathroom entrance (weird floor plan, I know).  We also plan on ordering a couple more sets to put up curtains across our bedroom windows (sounds like a no-brainer but again due to the odd layout of our unit, doing this was impossible with traditional window treatments and the limitations of being in a rental)!  
They were easy to install with two people but my roommate certainly could have done without my help.  I'm looking forward to learning how they hold up over time.  But will admit I'm curious how my hunt for curtains will go while being mindful of the weight limitations.
