400$ is an insane amount of money for this thing. I looked it up, its a custom built mini computer basically that runs the same thing a hacked firetv stick would. SO, basically your paying for the hardware, the software is free and anyone can load that on.
One thing to note about firetv sticks and these easytv's is that it WILL stop working eventually. Once the streams that the device's operating system pulls from get taken down then your thing is dead in the water. Could be a month, could be a day, could be 2 years.
