I have one of the Element extinguishers in each of my rigs. Hopefully never need them. They are small, don’t need recharged, and last way longer than a regular stingisher!
I really liked these and (like you said) there's no need to recharge them. I was disappointed to see the Element sticks didn't do well in a YouTube video by Harry Wagner where he tested 3-4 types of extinguishers.
