Whenever I passed by HYSSES Tanglin Mall, I can smell their Lemongrass a mile away. Today, I have decided to find out from the salesperson on how do they manage to scent their shop so strongly that I can even smell it from basement carpark. The salesgirl recommended this product, nebuliser and true enough, my living room is wonderfully scented with Lemongrass, making it feels like a resort. It is also very convenient to use where I just need to pour in the essential oils, turn on the knob and the machine starts working.There is an auto-timer to ensure efficiency of the oil used too. I am enjoying this machine so far.
