“The diffuser works great I got it as a Christmas present from my daughter with a Neom Calm & Relax oil which was very nice, I then purchased two more one of which is the above Boost your energy also Make you Happy unfortunately the aroma from the two I purchased hardly smell at all and keep getting more aroma from the original one I used even though I have throughly washed it and dried it these aroma are so expensive for 10ml so as I said in the title I am very disappointed with the performance of the oils.”
