BBE個CS幾好,買之前問咗好多關於安裝嘅問題都好有耐性答。師傅裝完之後,用落最放心係佢個密封式排氣,屋企有小朋友安全最緊要。恆溫好準,值得一讚。

Ja*******n 23/07/2025

恆溫係幾好,水力都夠。不過個聚碳酸酯面板望落有少少膠感,同埋開機下把風扇聲比想像中大聲。整體不過不失啦。

Er****o 06/08/2025

The entire process was smooth, from ordering on BBE to the free installation. The unit is quiet and provides stable hot water instantly. Highly recommended.

Mr. Leung 27/06/2025

特登加錢買埋個有線遙控,裝咗一個喺廚房,老婆煮緊飯都可以預先校定水溫俾個仔沖涼,個design真係好user-friendly。

Mrs. Ng 24/01/2026

個仔幫我換嘅,個數字mon好大好清楚,我唔戴眼鏡都睇到。一開就有熱水,唔使好似舊時嗰部咁等好耐,好方便。😊

Mr. Wong 27/01/2026

新屋裝修,個浴室好細,搵咗好耐先搵到呢部超薄款,真係好慳位。BBE送貨同TGC師傅安裝都好快手,服務一流。

Ca******e 04/02/2026

Love the minimalist design. It's super slim and fits perfectly with my bathroom's aesthetic. The constant temperature feature works like a charm.

P. F. Yip 05/09/2025

終於換走個舊爐!而家就算廚房開住水喉洗碗,沖涼水溫都完全唔會變,呢個恆溫功能真係解決咗大問題。

Fa******n 06/01/2026

白色面板好靚,機身夠薄。恆溫功能唔錯,CP值算高。不過約師傅安裝要等幾日,如果可以快啲就更好。

Mrs. Ho 03/01/2026

幫小朋友沖涼最緊要水溫穩定,呢部機完全做到。可以set到35度,夏天用都好舒服。買得好放心。👍

Ah****g 03/02/2026

終於換走咗個舊爐!呢部恆溫真係好好多,沖涼唔會再忽冷忽熱,個數碼display都好清晰。

K. Y. Lam 12/08/2025

Good for my rental unit. The 3-year warranty and free installation made it a very practical choice.

Eric 16/07/2025

Sleek and clean look. Doesn't feel bulky at all and the performance is solid. A good upgrade.
