Where can I buy one?

You can buy it directly from the company's website by clicking here.
NOTE: As it might get banned soon, people started to buy multiple devices at once as they want to resell them at a higher price later. So demand is crazy right now - please allow 1-2 weeks for shipping.

TVFrog even comes with an innovative remote/mouse for a new kind of user experience and a universal power adaptor and surge protector. So you can use it in any country of the world. Of course also with all cables you need to connect to any TV.
