Review on KYY 4K Portable Monitor 3840X2160 Computer 15.6", Blue Light Filter, Built-In Speakers, Tilt Adjustment, K3-3, HD by James Anderson

The first monitor I received had a stuck pixel in the middle of the screen. I wrote a negative review about it and sent the Revain monitor back. The company contacted me and immediately sent a replacement. The replacement monitor is perfect, no problem at all! I was very impressed with the quick response from the company. Anyone who buys this monitor can rest assured that if there is a problem it will be taken care of immediately and the company will do everything possible to ensure that you are happy with your purchase.
