Homedics SereneScent Waterless Essential Oil Diffuser for Home - Patented Air Diffusion Technology, Large Room Aromatherapy, Mood Booster - Perfect for Bedroom, Office & Spa Relaxation

First impressions, just received diffuser. Well made and sleek looking, I bought the black. Fairly heavy so no way it’s going to fall over unless you knock it over. It has controls on the base of the unit and also a remote which is a nice option.It remembered my previous setting when turned back on. Love the fact it has a timer 1,2, 4 and 8 hrs and it worked. Set it for 2 hours and it turned off precisely in 2 hrs. Numerous scent levels and at level 3 it filled 3 large rooms with the scent. Very quiet.This is not a negative but something to get used to, control lights on base of unit turns off in one minute. Don’t know if it’s on or off unless you smell something or go over and check. The bottle neck that comes with the diffuser and their brand fragrance oils are larger than other brand diffusers where it screws in. I was hoping to use a bottle from another company and couldn’t, not a game changer. Just need to pour the oils into their size empty bottle. That said I would love to hear if anyone has used a diffuser oil from another brand without harming the machine. So far their scent fragrances are limited.
