With two kids, we often have back-to-back showers. The 12L capacity is more than enough and the temperature stays perfectly consistent for everyone. The 60-min auto-off is a great safety feature.

Had a few questions about the top vent model. BBE's CS was very responsive and helped me confirm this was the right one for my flat. Great pre-sales service. The heater itself is fantastic. 👍
Mr. Wong
舊熱水爐時冷時熱，小朋友成日投訴。換咗呢部Rasonic之後，恆溫真係做得好好，水溫好穩定，開住水喉都唔會變。BBE送貨安裝夾得幾好，滿意。

My old heater would cut out on windy days. This Rasonic with the DC inverter fan is much more stable. Even with the recent strong winds, it works flawlessly. Gives me a lot of peace of mind.

The constant temperature feature works as advertised, which is good. However, the LED panel is very basic. For the price, it's a solid performer, but don't expect any fancy smart features.

揀呢部係為咗個ECO mode，用咗一個月，張煤氣單真係平咗少少。部機雲霧白個樣好簡潔，襯返我屋企個Muji-style design。BBE送貨都ok快。

格過幾間價，BBE算係幾抵。揀呢部係因為有1級能源標籤同3年保養，CP值高。恆溫功能比想像中好，希望可以襟用啲。

恆溫係幾好，但點火下下都「嘭」一聲，夜晚用有時會嚇一嚇。如果可以靜啲就perfect。除咗呢樣之外都冇乜投訴。

The slim design is perfect for my small bathroom. Love the cloud white color, looks very modern and clean. Delivery was next-day, very efficient.

買俾屋企人用，操作簡單，LED顯示夠大隻，老人家都識用。最緊要有熄火保護，用得安心啲。👍
Em******i
Works great, hot water is almost instant. The 'GU Mark' gives me peace of mind. A very straightforward and reliable unit.
K. Y. Fong
舊機壞咗急住用，落單第二日就送到。部機夠薄身，出熱水快，沖涼唔再忽冷忽熱。😊
Mi*******g
It does its job. No issues with installation or performance so far. Satisfied with the purchase.
Mr. Wong
師傅好準時，安裝快手又乾淨。部機出熱水快，搞掂。

Finally, no more 忽冷忽熱 showers! This thing is a lifesaver. ✨
