Good product, but service is questionable. Sent me a dead battery, when I called...they agreed to send me a better battery. But, wanted ME to properly dispose of bad battery. When I asked to send it back to them...they said that would be at MY cost. After I asked for a supervisor, the initial person finally agreed to send me a postage paid mailer. That took a Long time! As for product, works great but not easy to empty trash. Black rubber flap gets in way and clogs cannister when trying to empty.
