Ok I've had the Supbox 70W for half a day now so I don't pretend to be an expert. I'll cover the 2 main modes with my first impressions:
1) Billet Box mode- Interesting idea and flexible . You can use traditional boro tanks with your preferred bridge or you can use a tank like the Vapesnail or the equivalent "pod" that allows the use of Nord coils or the SXK drop ins. Clever.
I've only used the Vapesnail clone so far. It works ok but the main negative here is the airflow. It has to come in around the cage and as a result is less direct and a bit more restricted than with a Billet Box. Also the condensation build up underneath the Snail is considerable. Worse than a Billet Box.
So my first impression of Billet Box mode is that it's a good idea but maybe not fully thought out. I doubt I'll continue to use it much in this mode.

2) Atty mode - My tester atty has been the Dvarw DL. it's been my ADV for a while now on a Mixx and a Therion so it's a good litmus test.
When I first looked at it in position on the Supbox I thought the cage (made of some type of hard nylon/plastic -ABS?) would get in the way of the airflow.
This isn't the case. Air gets in fine and it vapes with no noticeable difference to the other 2 mods mentioned. This setup functions well. I like it and will keep using it in this mode.

My main worry here is again condensation build up. The photo below was taken after about 100 puffs of a 0.5Ohm build at 34W

The board -
It's a Sevo 70W board.The display reminds me a lot of the Asmodus GX80 board that SXK used in their older BB clones. The GX80 was renowned for reading resistance off and was a big reason for me only buying one BB clone.
The Sevo apparently doesn't have this problem. So far mine reads resistance the same as a DNA.
It fires fast and battery life seems ok. I haven't used temp control so can't comment on that.
Size and feel -
it's a fat little bugger. Already named it the Chunky Monkey. I've gotta say it feels good in the hand (mind/gutter).
Here it is in comparison to the Mixx -slightly shorter but thicker (mind/gutter). Definitely feels strong and comfortable. I like the firing button - well placed and clicky/responsive.

One negative is the finish.
It feels like the edges of the ABS body and the SS parts like the battery cap and threads are a bit rough. Nowhere near the quality of the Mixx.
Overall I'd say it's a cool idea and a fun little SBS mod with a twist. Probably a bit overpriced but it's got an addictive quality. The Chunky Monkey factor appeals to me. No way would you be likely to knock it over by accident.
I'm expecting it to be a durable, knockabout SBS with a cage that protects attys and a decent board
