新屋入伙買第一部冷氣，揀咗好耐。BBE送貨好準時，安裝師傅都好專業。呢部機真係好靜，開咗sleep mode幾乎聽唔到聲。最緊要係一級能源標籤，希望電費單唔會太嚇人啦。
Eric
The inverter is impressively quiet. You can hear the compressor spool up when you first turn it on, but once the room is cool, it's basically silent. The remote is user-friendly. A solid choice for a bedroom.

部機本身OK凍，但個size比想像中大，安裝要喺機背留好多位散熱，我個窗台差啲唔夠位。買之前最好度清楚尺寸。除咗呢樣，performance係可以嘅。

有小朋友，最注重空氣質素。見到有抗菌過濾網先買。四方送風好好，唔會對住個頭吹，小朋友都無咁易冷親。整體好滿意！😊

Replaced my old fixed-frequency unit. This one is much quieter and cools the room way faster. Good purchase.
