Review on NexiGo 2021 4K Portable Monitor Computer: Premium 15.6" Screen, Stunning 3840X2160P Resolution, PM4K15-AM02, HD Display by Jim Connelly

I do not recommend. A roughly $200 purchase stopped working after six months, although there were no physical defects. Suspected weak ports from the start. Brightness issue (too dark, the setting is off). --- I was able to get in touch with a NexiGo representative who promptly provided me with a replacement. The new block is excellent, there is no flicker at all. This can be a case of somewhat lax quality control (hit or miss). But I appreciate customer service and follow up.
