Great point.

Mines got wheels ftw!

and no more stairs. I usually drop it off in the morning then pick it up on my lunch.

Caps are better. I have to take the damn transfer device off every time I get that dewar filled. I know I'm getting it full, but it's a pita.

Biggest problem with a transfer device is you can't pour your unused juice back in the dewar without releasing pressure and removing the thing.

I hate when they fill it so the BOV are frozen open and they scream....cold air keeps jetting out therefore more and more frost forms on them and they get worse and worse lol gotta heat the valves till they thaw and shut down
