BBE CS was very helpful in explaining the right exhaust version. Delivery was next day. The quick heat system actually works within 3 minutes as advertised. ✨

T. K. Wong 21/02/2026

The EGO thermostat works great, water temperature is very stable. No more cold shocks during shower. Delivery was on time and packaging was secure.

Mrs. Lee 02/02/2026

BBE送貨好快。部機195mm真係好薄,裝喺廚櫃完全唔佔位。3分鐘即出熱水,唔使等咁耐,小朋友沖涼好方便。

Na*******u 08/02/2026

Love the ultra-thin 195mm design. It's the thinnest I could find in HK. Perfect for minimalist homes where you want to hide the heater.
