After the first battery charge, the vacuum cleaner worked well. I've tried charging the battery several times but it won't charge. It turns on and then immediately turns off again. When attempting to email the company using two different email addresses listed in the user manual, both emails returned as "address not found". Fake company? In the case of a low-quality product that doesn't last long after the first use and lack of customer service, I would advise ordering a vacuum cleaner from a well-known company or brand.
