Great for emergencies
I would have given this five stars if the female adapter had screwed on or clicked into place. Unless you fasten it down, it tends to come off while you are trying to position it. I used a bit of thermal plastic putty to permanently affix mine. (I would have used glue, but I was afraid it might melt the white part which seems to be made out of a thicker version of milk jug plastic.
