The GMK KD2 is one of the best portable monitors we've tested in terms of display quality and hinge rigidity. However, it falls short on its brightness claims while the slow black-white and gray-gray response times will sour many gamers.

Interesting bit of hardware. Sounds well suited for photo editing with the full Adobe RGB coverage. The response time doesn't matter in that scenario.
We believe in long term relationship with our customers, Because we don't want you to buy only once from Electro City and not come back to us again and spread a bad word.
