Here is my review of the eye-one display 2. Overall it has made my all my monitors closer to the same colors temperatures and brightness than all the by eye trying I have done before. That said it sill is not quite the same and I suspect that is because different monitor's. I would suspect that with this being an older model the newer ones might be more accurate. But I would say for the price I got this it would definitely be worth it. If anyone it interested in seeing a tear-down of it please not in the comments. Website: www.serpentofthenight.com
