    The geyser system worked brilliantly on my road trip through Nevada and California. It’s an outdoor minimalists’ dream

    Overlander game changer ! I used to carry 20+ gallons of water for a weekend getaway. Not any more! The geyser system is so efficient with its use of water, I no longer have to stress about how much water I use when showering, doing dishes etc. Money well spent !

    I purchased the heated model last year and after some extended field use its held up well! Dramatically lowering water consumption, so less hauled. I heat water by activating about an hour before making camp or if I’m in a hurry I’ll heat with a camp stove and Nalgene method. Very rugged unit with lots of safety, replaced my zodi unit. If you can afford it you won’t go wrong.

    Got the hot water system on Black Friday sale. I filled it with the outside water hose, and it took 35 min. to heat up to temp. I wanted to have a backup system in case something happened at home and for camping as well. Haven’t had a chance to field test it yet but I’m not too concerned based on all the positive reviews. I like having kits ready for specific needs and this system fit perfectly in a Pelican Vault V525 case.

    So far very happy with the system.

    I have the heater model and love it. Don’t know why I waited so long. I have used it all year and wether it’s hot out or cold out the Geyser is fantastic. If your thinking about it, get it!

    This is the shower I was looking for on my trips. Compact, efficient and leaves you feeling cleaner than shower wipes. Less than a gallon of water used each time means I don’t need a huge tank of water.

    Great system, we have multiple ways to shower and this is by far the quickest, nice product.

    I was first introduced to this shower system at the Overland Expo in Flagstaff and I was so impressed I wanted to buy it on site. Sadly they were out of stock but ordered one before we left the expo. Since then we have used it multiple times on overland trips and now I can’t imagine not having it. One of the best shower systems that utilizes very little water. I will also be doing a review on my YouTube channel as we now own three of these within my family. Amazing product.
