I've heard bad thing about the original Gizzmo IBC, but this model seems to be good.
It has closed loop boost control, which in my eyes is a very good thing (a lot of EBCs dont have this function)
Plus it has the good ol scramble mode, so you can bump up the boost for a set amount of time.
And another big selling point for me is it doesn't stand out like dogs balls and I can also use it as a boost gauge.
Anyone using one of these? Are they all they're cracked up to be?
