Well, to be honest Viktor... it only looks nice, that's all.
During maintenance and cleaning it is more or less a drawback as you can't move the light to the back of the tank (like you could do with the "old" 601).
And you have to clean it at least once a week.
If the scape has a nice colourful stem-plant background then it looks really nice.
But I'm really wondering how it will look with an Iwagumi type scape.
Overall, I would not pick it up next time. It's more ore less a nice gimmick.
Apart from that, I'm really happy with the new light unit!
