i bought viewshocker before. I am not sure which brand is the best portable monitor in the world, but viewshocker will be definitely the best choice for me. I was looking for a cheap monitor for my business trip. Asus and Lepow are great. However, their price are kind of unacceptable for me, therefore i went to find the manufacturer of portable monitor. Then viewshocker just appeared.
cheaper while it has great color gamut and contrast ratio, you can google viewshocker portable monitor or just go to their webisite:www.feilitu.com
