The 360-degree installation is a lifesaver for tight spaces. Installed it under the bathroom basin. The bare wire heating tech is efficient, giving instant hot water. BBE customer service was very helpful in confirming the electrical requirements before shipping.

Love the eco-friendly aspect. No standby energy loss like traditional storage heaters. The packaging from BBE was very secure with minimal plastic waste. Highly recommend this Stiebel Eltron model for handwashing stations! 😊

屋企水壓不嬲都弱，呢部2L/min就啟動到真係救星！即開即熱唔洗等，機身又輕巧。BBE送貨仲快過預期，尋日落單今日晏晝就收到，好滿意呢次網購體驗！
Mrs. Wong
包裝好安全。呢部4kW機仔細細，用嚟洗碗洗手就一流，即開即熱。但如果想用嚟沖涼就唔多夠熱力，冬天會唔夠用。大家買之前要問清楚CS用途先。
