J.and,
First - Welcome to Reef Frontiers!!!
The Odyssea is a cheap, inexpensive starter light. If you are starting a tank, the initial output can be quite intimidating... and having something like the Odyssea lights sure help with that.
As long as you understand their lights do tend to lose spectrum much sooner than some of the more expensive brands... and you plan ahead and purchase new lights at about a 6 month interval, vice the typical 9 to 12 months... all should be good.
Personally, when you do replace the lights, order the more expensive ones (hellolights.com has great pricing, by the way)... then you'll be able to go to the longer replacement schedule.
The only other complaint that I have heard... is the ballasts tend to not last "as long" on these units. However, I have heard of several people that have now had their units for about 3 years, original ballasts... and all is fine for them.
