I've been watching this thing as it slowly rolls out and I am intrigued. It's like an egrip but with a replaceable battery and larger
tank. I suspect that it is mostly a subox with an internal subtank (but TC capable) and will be 3.25" X 22mm X 3" or so. I bet the price will be around $50 all said and done. If it has an rba similar to the subtank and also works with VW, I'll be in the market for sure. I am a bit concerned about how to fill it. The egrip has a little door on the side but I don't see a way to fill this other than removing the bottom (like the subtank). That might kill it for me.
