I bought my first shark 10 years ago, fell in love the first use. About 3 years ago, I upgraded  shark duo and just recently the shark deuo Apex stick vacuum. Im not as impressed as I thought I would. It heavier then it looks and not easy to use. The two attachments are useless so cleaning anything other then floor is not something you can do. I still clean hair off the heater bar, not nearly as often as my other vac so that's a good thing! It cleans really well, I just wish I would have bought the upright instead!
