This has been a very useful purchase.  I bought a refurbished machine to save a bit of money and it looked completely new to me.  
I've steam more items than I ever thought possible!
Like others, I wish it had a water level window as well as an easier place to wind the cord.  I never wind it underneath as suggested; its too awkward.  I also would like to have some sort of mechanical handle to change the steaming/scrubbing angle at times.
