Yay! It showed up!
It's a really nice device. I added one thick o-ring to whatever was already in there and have a total of three washers on the post to fit it to an AW 2000 mAh IMR. I might add one more washer for a nice short throw. The button isn't quite as smooth as a P+ (duh) but very nice, the spring appears to be the same as a P+ and the pressure is the same. Changing the washers was a bit hard until the Eureka moment hit and I figured it out. Very light and excellently finished. The low-tech adjustable post appears to be very sturdy and requires minimal adjustment, I think it will withstand the test of time.
My bottom button is perfectly flat and sits rock solid, but if there was a heavy atomizer on it I'd be very wary of sitting it upright unlocked. I'm not sure about unlocked pocketability, I do that all the time with a P+ but this one maybe not since the button has no protection.
Edit: I just found out, do not carry your Simplicity in your pocket unlocked.
