新屋裝修，個廁所唔大，搵咗好耐先搵到呢部夠薄身嘅熱水爐。140mm深度真係fit晒位。雲霧白個design好簡約，同我哋個浴室vibe好夾。最緊要係恆溫好準，沖涼唔會再嚇親。
Mrs. Wong
屋企個舊爐壞壞哋，即刻上BBE買。送貨勁快，兩日就到。而家幫小朋友沖涼放心好多，個智能恆溫真係掂，唔怕水溫突然變凍變熱。有埋多重安全保護，用得好安心。👍

The Japanese CPU isn't just a gimmick. The temperature control is incredibly precise, you can feel the ±1°C accuracy. A huge tech upgrade from my previous heater. Very stable.

買之前問過CS，確認係背出式啱我屋企用。個款夠晒slim，白色好靚。恆溫功能一流，加上有3年保養，新居入伙用都放心啲。😊

The slim design is a huge upgrade from my old bulky one. It frees up so much visual space. Constant temperature is a game-changer. Excellent value for money.
Mr. Leung
屋企人多，以前個爐沖完一個要等陣。呢部10公升出水量好足，連續沖涼都無問題，水溫keep得好好，唔會搶水。

Bought this for the Grade 1 energy label. The old one was a gas-guzzler. This one heats up fast and is very efficient. Hope to save on my bills.

買嚟放租用，最緊要安全耐用。信興牌子有保證，多重安全裝置，租客用得安全，自己都唔使煩。

部機本身無問題，恆溫OK。但係BBE約師傅安裝要等成個禮拜，有啲耐。如果急用嘅話要諗諗。
T. C. Wong
Very quiet operation compared to my old unit. The continuous pulse ignition is instant and reliable. Good build quality.
K. P. Cheung
恆溫真係做得好好，火力都夠猛。唯一係個操作panel有少少膠感，不過呢個價錢都收貨啦。
T. M. Fung
Instant heat is great. The Grade 1 energy efficiency label is a big plus for me. Solid performance.
