not tried it yet, but one request
"I haven’t used it yet, since it’s really part of an emergency kit for more people. I notice that the top on this unit is screwed down instead of clipped as in the instructions, which I expect is an update that hasn’t made it into the drawings yet. What I’d really like is some way to store the gray external tube securely and cleanly, clipped to or inside the main unit box. Right now it’s loose, which seems like an invitation to lose it."
