Mr. Leung
買之前問咗BBE CS好多安裝問題，都好有耐性答。換咗呢部機，最大感受係個恆溫，以前舊機成日搶火，水溫忽冷忽熱，小朋友沖涼好牙煙。而家set好溫度就唔會變，±1℃真係好準，安心好多。
Marcus T.
Very impressed with the specs. The Japanese CPU ensures precise temperature control, and the DC inverter fan is a huge plus for high-rise buildings like mine. Solid build and performance.
Ms. Fong
The constant temperature is great, no more sudden cold shocks. But the fan is a little noisy during operation, louder than my previous model. Overall it's okay for the price.

有兒童鎖功能真係好好！唔怕啲細路手多多亂咁㩒校到水溫太熱。沖涼時恆溫又夠準，屋企有小朋友嘅話呢個safety feature好重要。✨

喺BBE買完直接約埋安裝，師傅好準時，手勢好快，價錢都公道。部機用落暫時滿意，恆溫快，希望真係好似佢講咁慳到gas錢。
Mr. Leung
住高層最緊要安全。見佢有抗強風功能就買，個直流變頻風機聽落好pro，打風落雨都安心啲。恆溫系統好穩定，值得推薦。
S. L. Chan
送貨等咗幾日。部機恆溫做得好好，水力都夠。唯一係點火下下都幾大聲，嚇一嚇，習慣咗就冇嘢。整體滿意。😊

見佢有1級能源標籤同ECO mode先買，雖然機價唔算平，希望長遠慳返啲煤氣費啦。出熱水都快同穩定嘅。

Bought this for my rental property. Rasonic is a reliable brand and the 3-year warranty is a key factor. Good value for money.

Fits perfectly in our small bathroom. The slim 150mm design is a huge plus for saving space. Delivery from BBE was fast too.
Alex P.
The digital display is clear and user-friendly. Setting the temperature is straightforward. Good UI design.

The auto shut-off feature after 60 minutes gives me peace of mind. Feels much safer than my old model.
Mrs. Ng
師傅裝好一開即用，水溫好穩定，幫BB沖涼方便好多，唔洗再溝冷熱水。👍
