Okay, so I've been using this electric tankless water heater for about a month now in my small apartment, and here's the real tea ☕️

First off - the INSTANT hot water claim? Mostly true! It heats up crazy fast for my kitchen sink and bathroom. Though heads up - 'instant' means like 5-10 seconds, not magically-hot-immediately.

The Celsius-only display had me doing metric conversions at first (why no Fahrenheit option??), but you get used to it. Pro tip: 40°C is perfect shower temp!

Installation was... an adventure. The manual's wiring instructions are WRONG (dangerously wrong!). Had to call an electrician who confirmed it needs proper 240V setup. Don't DIY this unless you're super confident!

Space-saving design is legit - it's smaller than my microwave! But temper your expectations - this ain't gonna power a whole mansion. Works great for 1-2 faucets max.

Biggest surprise? The energy savings! My electric bill dropped about $15/month compared to my old tank heater. That self-modulating tech actually works!

Would I buy again? For $99? Absolutely - but ONLY if you're handy or willing to pay for professional installation. And maybe keep a Celsius conversion chart handy 😉
