Comparison.
I own a Companion Cube hot water system however recently I purchased a Colman H2o as the Companion has let me down twice while camping. On comparison the Companion has slightly better water pressure. The water flow on my Companion can be turned on and off at the shower head without the unit turning off. I've found for no reason the C/H2o just turns off for no logical reason mid shower. Because of the poor water control while the C/H2o is operational there's far great water wastage. The C/H2o doesn't want to heat the water higher than 50c. They both achieve the best result by pre-heating the water in the contain to the desired heat prior to the shower. I'm not happy with either however I'm sorry I purchased the Colman H2o.
