I have owned mine Mighty Mite for 5 years.  My review can go either way so I gave it a 4.  It all depends on how much noise you can tolerate.  It  is very noisy!  When I use it I wear ear plugs.  Other than that it is a terrific vacuum cleaner.  It has pretty basic features, but everything still works after five years.  It is so light that I just carry it around as I vacuum which is much easier than pulling it.
