which LED unit to buy....

[Reef Pilot]

I've had my Radions (3 of them) for almost a year now, and they work great. Only problem has been the software to program them. Takes a bit of fiddling, and can cause problems if you screw up. But once you have it figured out, no sweat.

I have followed the forums on RF about them, and I can certainly see how a lot of people have trouble with them. But if you are half a geek, you should be OK. While I have not had to call or email them for support myself, apparently they are very helpful, and don't hesitate to replace a unit if you can't get to work properly.

So I wouldn't hesitate to buy more. I will see what the boxing day sales are, and might get a Gen 2 set for my new downstairs tank.
