Hi Sanj. Thanks for your message. Since Wattvision hasn't launched yet, I don't want to get in to too much detail, but in short, wattvision is faster, better, and cheaper. You'll hear more when we launch soon. Thanks for your interest. Do hit up the team at info@wattvision if you want the details ;) -s
