Yeah, Kessil is a small part of Dicon, which makes a lot of led's for commercial and professional use. The great thing about them is everything is done in-house (except assembly?). I actually like the hardware controller, especially for lighting. I don't like to play around or change a lot of settings for lighting. Simply set the color and intensity and be done, step back and let it work. I think it's one of those things that left in the hobbyist's hands can cause too many problems. I've seen too many posts about led's (especially Kessil) not being strong enough or good enough to grow sps, it's simply untrue and unfortunate, but the sheer ignorance on the users side makes them believe that's the case.
But hopefully they'll release the dongle soon, but I'm not holding my breath. [emoji16]
