The Shark vacuum was very easy to put together.  It only took about 10 minutes after I had read the directions.  It is very sleek and isn't very heavy.  I was pleased that it was so easy to move around.  
I was in shock when I saw how much dirt and fur it pick up.  I thought my old vacuum was still doing a pretty good job the plug on it had just gone bad.  I was completely wrong!  The Shark hands down did an amazing job.  It makes me want to vacuum!   If your shopping for a new vacuum check this one out.  I don't think you will be disappointed.
