I don't feel so bad that I just today got around to trying out the ethlargement pill on two very different 1080s and all I can see is, "holy frijoles!" On a 2+ year old EVGA Founders Edition, Ethash went from a pathetic 21 MH/s to 30.5 MH/s and power consumption dropped about 40W. Next I tried it on a much newer Asus RoG Strix 1080 mining CryptoNight (not ideal, I know) and hashrate went from about 540 H/s to about 630 H/s.
However, trying to increase the memory clock rate by +100 caused the FE card to crash so hard I had to hit the reset button. So, be very, very careful with the overclocks while on the pill.
Well, if you don't mess with mem. clock rate too much, and instead bump up the TDP slightly to the 70+ range, on 1080 Ti's pretty easy to get over 50 MH/s on Eth with minimal fuss.
Haven't had any bad crashes using it yet, but I stopped adjusting settings once I got to 53-55 MH/s on Eth.
And yes, I actually donated -- sounds like very few did.
