We purchased this product on 03/27/18 and it was delivered on 04/02. We started using it by 04/04. Initially, it worked great.However, after barely 3 weeks, it stopped working. It appears that the battery/charger was defective.The manufacturer is horrendous. They never respond to any customer inquiries.When we call the customer line, only voice message picks up with no follow up based on our message.We did not get any response to our emails or the inquiry we made per their website.We now ended up with a broken machine and our money got wasted. Please stay away from this product. Or buy it if you only would like to use for few weeks.
