Agree. I have an array of Radions over one tank ranging from Gen3 Pros to Gen 6 Pros. The corals have no idea that I cheaped out on them by going with used products. I've never used another retail LED system, so my bias is for Radions because they've worked well for me and didn't cook my tank like halides did. Beyond that, I can't recommend another brand.The funny part is every single one of us in here is biased. We all have products we’ve used and loved and will “push” those products. We also have products we had a horrible time with and will warn others to stay away. Over time a lot of us have success with the same brands over and over and we are bias to them.
That's similar to what Ryan said in his video. Go with what gives you the results you're after.
