Ive seen some guy on grasscity pulling 400g + from just one of these in a 2x4, so apparently these are 1.8 umol/j (actually emitted and measured, none of that theoretical value crap) I'd say it's a good option for those who don't want to wait for the boards from China. Even Migro dude was positive about this fixture.
Alternatively the driver can be unplugged and used on better boards in future. I was gonna order 4 fotops 800 boards and DIY but im gonna buy this one instead. Half the price and I'll have two tents so I can propagate and shorten time between harvests. Once my bloom light fails I'll be looking at QB's. By that time they will get even better
