Purchased three months ago.  I am very familiar with Shark vacuums seeing how that is all I used for the past 20 years.  Shark has done it again with providing power, size and mobility.  I gave it four stars only because on other models, when you removed the to handle to clean with attachments, you had a LED light on handle.  The LED lights are amazing and take the Shark to whole new level.  Not sure why this option was omitted seeing how it has been on older models.  Thank you Shark!
