Mrs. Wong
屋企有老有嫩,最緊要係安全。呢部樂信熱水爐有60分鐘自動熄火,恆溫又做得好好,唔怕啲水會突然辣親小朋友。BBE送貨快,約師傅安裝都好順利,成個體驗唔錯。

Purchased this for a rental flat. The key selling points for me were the multiple safety features like the 60-min auto shut-off and the 3-year warranty. Gives me peace of mind. A solid investment.

新屋裝修,揀家電最緊要個design。呢部雲霧白真係好靚,同我哋個minimalist廁所好夾。用落恆溫好準,沖涼唔會再忽冷忽熱,個vibe即刻高級晒!✨

Product itself is 5-star, very stable temperature. However, the third-party installer arranged by BBE was late by 2 hours, which was quite inconvenient. Just be aware of the scheduling.
Mr. Ho
買之前問過CS安裝問題,答得好詳細。用落發現個智能分段火排真係有用,夏天用好少火就夠熱,應該會慳到煤氣費。恆溫控制好stable。
Mr. Leung
Works as advertised. The constant temperature is very stable. Installation was arranged by BBE and went smoothly. Overall a solid and reliable product.

The ±1℃ temperature control is impressively accurate, thanks to the Japanese CPU. Very smart machine. ✨

Very efficient and quiet. The 12L capacity is perfect for my family. BBE delivered the next day.
C. F. Ng
The unit is a bit louder than my old one when it ignites. Not a dealbreaker, but noticeable.
T. C. Mak
Bought this for my rental unit. BBE delivery was fast and the 3-year warranty is a big plus.
