Works perfectly. Less than 3 months. Now I'm waiting to hear about that "1 year warranty" and how to get it, otherwise it would be a waste of $20 again, I will never buy a vacuum cleaner that requires a charger again! more things can go wrong / break = more $ more $ more $. I hope this company lives up to their word/product. I'll update as soon as I have an answer/solution. Updated: I upgraded from 3 to 4 stars. I'm still upset that the original charger broke within 90 days of use, but Revain// seller sent a replacement. Let's see how this ROUND 2 goes. Will be updated again; if there is any problem with this replacement lol
