The device they are selling sounds too good to be true - and it probably is. What I am 100% sure of is that their discounts aren't what they claim. Do to the math - the "70% off" discount isn't. Nor are any of the others. The first time I visited the site, one offer was for "85% off" - but anyone with 3rd-grade math skills could see it wasn't true. I'm attaching a screenshot showing some of the offers and how they don't add up.
