I was directed from an Instagram advertisement on this site that promoted the limited offer for PowerWatch2 watches at a price of only $ 0.01, which turned out to be a scam, an aspect confirmed even by the official customer support of MATRIX PowerWatch:
"Thank you for contacting us and letting us know about the site. It is indeed a scam website. We have been trying to take these sites down with no avail. This website does not represent PowerWatch.
Please note that PowerWatch is only available on https://www.powerwatch.com/ and soon to be on Amazon. Any other site purporting to sell PowerWatch is most likely a scam, especially if they are selling it for a cheap price."
