great product with great power! product arrived on Friday, Saturday morning I could not understand why it did not light up, I sent an email thinking that before Monday I would not receive an answer, to my great regret since I would have used the whole weekend to clean various areas of the dirt of the home! instead after not even once we have already noticed one of my mails it indicates the possible reasons why the machine did not turn on! security didn't start the car because there wasn't enough oil in. i love motor! congratulations to customer service! highly recommended !!
