Yep, agreed to everything. One broke, immediately got a replacement! They are awesome.
I have the cloth case thing with the straps and buckle. It holds extra pads (I wish it held an extra butane cartridge) and I just clip the buckle around the shoulder strap of my vest with the grate facing up. I only turn it on when I'm sitting and that can get kind of hot but I don't have to worry about it because when I get up to go and shut it off, it just hangs outside my vest.
