Let me start by saying this little gadget has been a lifesaver during winter mornings when my regular water heater decides to take a vacation. The first time I used it to heat a 5-gallon bucket for an outdoor shower, I was shocked (not literally!) - it brought lukewarm water to a perfect steamy temperature in under 10 minutes. That porous stainless steel design really does its job well.

However, it's not all sunshine and roses. Like one reviewer mentioned, the Celsius-only thermometer drove me crazy until I found my kitchen thermometer. And that cord? Way too short! I've had to use an extension cord every single time, which makes me nervous about safety despite their claims of overheat protection.

The real test came when my bathtub heater broke last month. While it did eventually warm the water, it took nearly 3 hours for a modest temperature increase - definitely not the 'minutes' promised for larger volumes. For small quantities though? Absolute champ. My current routine involves using it for spot heating while keeping pots on the stove as backup.

Would I recommend it? With caveats. For quick small-batch heating (dishes, outdoor showers) it's fantastic. For serious bathtub-filling duty... maybe keep your stove handy too.
