I have owned about 4 Monitors all within this price range, and of the four this was my favorite. It has been reliable, sturdily constructed, even when it fell over after an earthquake.
It turns on quickly, has many presets for specific uses e.g. Gaming, Night-Mode, High Brightness etc.
One thing that annoyed slightly was the position of the plugs for various cables as they were quite high up the back of the monitor, making it difficult to connect things quickly, like a laptop that would frequently be coming on and off the monitor.
Overall, very good. I would recommend this to anyone looking for a larger monitor, or an upgrade from a store-bought desktop PC.
