Go with Robo's.. Find a single complain. He runs his business like Donald trump. Everything calculated.. Amazing products.. I use him. Robo never dropped off the map, always communication is great...
Black Widow had had many, many issues.. "personal" hair in his vials.. Etc...
I understand your analogy but didn't Trump file for bankruptcy and have illegal immigrants working for him? Personally I ordered from both and never had a problem with either. But I will put out there, you take a risk with any lab. Really who can you trust unless you are brewing your own shit.
