Checked with BBE sales beforehand to confirm my flat's 3-phase power requirement. The 3-year on-site warranty gives great peace of mind. Excellent water pressure and instantaneous heating.

BBE送貨準時,師傅裝機好快手。部機幾compact唔阻掟,開水幾秒就熱,三段溫度35度同45度最常用,沖涼唔會忽冷忽熱,夠穩定。

Works well. Only three preset temps to choose from, but 45 degrees is just right for winter.
