I purchased Lemongrass Diffuser + Neroli Diffuser + FREE Lemongrass Soap and was disappointed that the scent was not as strong as expected, however Charlotte from customer services was very fast to respond to my email and rectified the situation for me, I was impressed with the level of customer service and also my replacement diffusers, so much so that I ordered another one. I will be buying more for Christmas presents and highly recommend this company and its products.
