I received the 120ML Aptoyu Aromatherapy Essential Oil diffuser free in exchange for my unbiased honest opinion. I love essential oils and there essentials to go with them. This diffuser works really well. You can allowing it to flip through the different colors of lights, set it on a specific light, or keep the light off. You add water with your drops of choice oil and turn the diffuser on. You can manually shut it off or it will shut off automatically when it runs out of water. I haven’t had any issues with this diffuser with daily use for the last week. It fits nicely without taking up too much space anywhere you want it. It’s great for many of the different benefits that essential oils give but I use them for the aroma not well knowledge of the many benefits.
