I had heard good things about the Shark lift-away vacuum cleaner and was in market for one since my Oreck had just died.  Wayfair had the lowest price by far and ordering was easy.  I received the product sooner than I had expected and I couldn't be happier.  So far this is the best vacuum cleaner that I have ever owned.  If you are looking for a new vacuum cleaner, I recommend the Shark lift-away, and I recommend that you buy it from Wayfair.
