I don't own radions anymore, but I just don't comprehend purchasing Reeflink. Wireless connection should be standard in high end LED lighting fixtures, not a $200 upgrade. Also many users have a controller like an Apex which can control the lights anyway. The Reeflink seems redundant and very one dimensional to me. ESL is a nightmare to work with, and is the reason I sold my radions. Who needs cloud based lighting? My money goes towards an Apex and WXM. Just my opinion.
