I don't see what's wrong with price comparison? If you search for the highest prices, then more power to you (if you're convinced that nullify's scams), Ill continue to let price influence my decision, especially when they claim money back if they are not identical items and after I tell them I will be testing them.
Scenario:
Buy 304 boards without 660nm for [($47 + $39 for heat sink + shipping) + (~$40 for 660nm)] × (θ).
~$126 × θ
Buy 304 boards with 660nm for [($50 heatsink and shipping)] × (θ)
~$50 × θ
They are C chips, so it's the difference between s5 and s6, or what people have stated as a 5-7% difference in effeciency.
Ill pay $50 + testing fees on the chance of a total cost of $400 vs $1,000. That's a $600 difference in only 2 tents. Spend $150 to make $450 is 3 ($450) to 1 ($150) on my money, if there's a 1 in 3 chance they are s6 then that bet breaks even.. and an educated risk. Plus s5 is pretty good as well if shit hits the fan and I don't get a refund. So there is only upside minus the cost of the test and initial board, imo.
This scenario was only 2 tents and you can see that the extrinsic value of a test like this grows with the order size. Ie the cost to benefit ratio decreases. Imagine the possible order size is this entire community and you can see the cost to benefit ratio is also very small. That's what we do here, we submit data to make a larger collective so that we can all draw on everyone's efforts instead of just trying to acumulate knowledge by self discovery or solo experiences (not talking about masturbation lol). It's just a piece of the archive.
Is 5-7% effeciency increase worth double the money? Because I'm a hobbyist Ill spend a little extra to find out how big the difference is before I hall off and pull the trigger on a bunch of the name brand..
Is it a waste of money? That will depend on what the test says and if they are bound to honor their word if they come back as s5. Will they still grow plants? Yep. Is it about getting genuine chips for you? No not really, slightly, but more or less the principle of the matter, and the data from the vis/non-vis ESD chip testing as well as definitive proof in what I have.
