By a portal shower OP, I picked up one of these beauties on the road side pick up last week. It will be christened on our next camping trip. Did a test run with it and it "showered" for a good 5 minutes before running out. Amazing really since it is only a 12litre container. Best thing about it, you can put it on the fire to heat up, no need for those black solar plastic showers.
Worst thing about it though would be the cost in buying one. They are quite hefty on the wallet.
