I was replacing a Red Devil cordless that broke in the middle of the handle and my research told me this was a similar product at a similar price.  I was very pleased when I used it the first time that it is really able to suck up small items from the floor.  Sometimes it takes a second swipe, but it does get the job done.  Battery life was a concern too, but I found I can cover my living room, dining room and kitchen before it begins to slow down.  Since it included a second battery, you can continue to clean if you want to.
