I've been using this product since 2012 and it still going.  Better than the upright vacuum that I have that I have to replace at least once a year and it cost more.  I use this to vacuum the stairs and upstairs bedrooms as they are all carpeted and we have 2 mutts that sheds so much. I can vacuum all corners, hidden/hard to reach places, blinds and annoying cobwebs. The vacuum bags are also reasonable. I think that this is an excellent product overall.
