We've only used this once so I can't say how it will hold up to multiple uses over time. Out of the box it appears to work as described. The hose was a little tricky to install at first. It does make hot water, but it also cools off pretty quickly. It's amazing to take a hot shower when you are roughing it on a camping trip. We didn't have these when I camped with my family growing up and this is certainly a game changer and made our latest trip so much more enjoyable. Taking a hot shower is what you miss most when camping so this really makes the adventure that much more enjoyable. I hope to get many years of use out of this new useful device. So far the quality is good and it works as adsvertised. Can't wait to go camping again!
