They advertise a smart watch that lists sleep monitoring, "live" heart rate, blood pressure and blood oxygen monitoring, and a host of other non-existent benefits. The heart rate monitor isn't live, you  have to press a button and wait 30 seconds to get a reading. This is not live, and is also not accurate. Be aware it does NOT GIVE YOU BLOOD PRESSURE OR BLOOD OXYGEN LEVELS. The watch is more like a childs toy than a smart watch, it is very poor quality and cheap looking.  I complained about the false claims regarding this item, and told them I wanted to return it. They agreed, so I returned it registered mail (at my cost) and was told that my refund was processed. 2 months later, I am still waiting for the money. They have all the lies and excuses under the sun. "Please wait a few more days, as sometimes refunds can take 30 days" or "Because of the payment system you used , this has delayed the refund process" or they give you a fraudulent code that they tell you to check with your bank. DO NOT DEAL WITH THIS COMPANY. SCAMMING THIEVES. They will not refund your money, no matter what they say.
