Himalayan bells, eh? The guys running these scams are pretty creative, you gotta give them that. They may even have a sense of humor...

The 1% who get fooled more than pay for the 99% who don't.

"Expect improvements in all aspects of the device! With phones, better reception, longer run times between charges, cooler operating temperature, faster app loading, and gaming response! And of course, improved picture and audio".
At least the old time snake oil sellers used to put on a bit of a show. These schmucks aren't even trying.
