The case seems like it will protect my Apollo Twin as I want it to, however the little place where you're supposed to put the USB/Thunderbolt cable and/or the power supply is not big enough. I was not comfortable with putting anything in there. Putting in only the cable might be okay, if you coil it small enough, but definitely not the power supply.
If I already have to carry the power supply somewhere else, like a backpack for example, then putting only the cable there does not really make much of a difference.
Otherwise the Apollo Twin fits like a glove into it, it does not rattle when the case is closed but stays firmly in place.
