Great essential oil diffuser
This product is  exactly the same as the Welledia 1800ML diffuser and $6 less in price, I bought both at the same time and was very surprised to see the same product besides the name Welledia below the front knob the led color above the knob is green and blue on the Newstyle and both turn red and shut down when empty. Both products work good as a essential oil diffuser and love the fact you can turn the light on and off. Both have variable adjustment of amount of water vapor output but find fan does not change speed as you increase the amount of mist which can be so much it tends to sink down like a cloud instead of rising. You can play with the output knob to get your desired flow. This just shows how powerful the ultrasonic plate is. These two products (being identical) are both heads above the Young Living diffuser which I had to replace due to failure at less than half the price . I highly recommend these two products but save some money by buying the Newstyle brand. One came in a fancy box and the other came in a plane box. Both hold the same amount of water even though I have not measured either, the dimensions are the same and hold enough water to last 6-18 hours depending on the flow rate. I love the fact you can add the oils and water, put the cap on and shake it to mix the oils before placing it on the diffuser plate. No, the led above the knob cannot be turned off but a piece of electrical tape over it does the trick. UPDATE, TO USE BEST AS AN ESSENTIAL OIL DIFFUSER, PUT OILS DIRECTLY IN THE BASE AFTER IT HAS WATER IN IT NOT IN THE TANK. This will concentrate the oil diffusion better into the air and when the oils have been diffused will keep working as a humidifier. Add more oils as needed to the base water but MAKE SURE you turn off machine before you lift tank off to do this or splashing of water will occur.
