I be so po would I waste $ 57 on this . I buy this to dust around the comp. , phone , printer , etc. on the desk and because it get a 4 star rating on 85 hit . let that be a lesson . I agree with the bad review . short run time , long charge time , plus ergonomically awkward to use . I put a shoulder strap on it -lrb- need a hand free to move stuff -rrb- and a better brush head but the short run time -lrb- 5 min ? -rrb- and long charge time -lrb- every time , not just the first time -rrb- still make it a bust . build quality seem good so maybe it 'll work for someone with different need than I . in they defense , I have a B&D; Dustbuster floor vac that I love and run 4 time longer even with the powerhead go .
