I have one for about 6 weeks now and it's brilliant! Currently just has the clowns and LR in but was setup since October in my shop. I'm getting the first inverts for it tommorow. I think they are great systems. Interpet (owners of red sea) are currently shipping out new hoods for every system because of ballast problems with the lights and over-heating problems and noise problems with the fan. Although, I believe they are using customers as guinea pigs which I don't agree with, it is a good system. Chances are if you buy one now it will already have the new lid. Also, check the skimmer as recently a new attachment for it was sent out for all exsisiting models becuase the skimmer wasn't working properly. Again, if you buy a new one, it should already be sorted. I'm having great success with it and my customers at work that have had one are also enjoying them.
