I guess I need to word things differently as definition of a word eludes some.
I said it appears that they are apollo rebrands. As in appearance.... My "None of us" comment still holds so far that since none of us have any knowledge to the differnce in components because no one with a KIND is willing to rip it open and void the waranty, which is 100% understandable. Hence the none of us know the actual differences. Again like I said those who are using the KIND are not experiencing all the issues common with the apollo. So something must be different. What? We don't know at this point. Until someone knowledgeable on the subject matter dissects the two and compares.
As a couple members have shown that work. Though for the watts and price as I mentioned you might look into the others like AT, A51, and RAPID if going for something other than DIY.
KIND works, but the best? Nope. What's the best...? can't really say. Until we all run the same strains with the same nutes and health in the same environments we can't really say. DIY is the best bang for the buck minus the warranty. Next ONYX from rapid led. Then A51 and AT are pretty similar when it comes larger than 2x3. If 3x3,4x4+ At and A51 are pretty similar with the deals they offer. Onyx would still be the cheapest, though you could run more watts for the same output from what I can tell at this point in time. i could be wrong... But again Time will tell for that as wel.
