I am very disappointed with
I am very disappointed with the macro diffuser purchases, I bought 2 of them online. The macro diffuser make such a loud noise its impossible for anyone sitting within the room not to notice to see what that long hissing annoying noise. I had requested scent Australia for help to help me reduce the noise and to even more disappointment they asked me to buy quite diffuser (element) I was not expecting them to give me such answers than resolve the 2 macro purchases I had made. i have now disconnected both the diffusers and put them back in the boxes with utter waste of money and never to be used diffusers. Think before you buy any diffusers as they will not refund as they even advised as this is been used and cannot be refunded. Very bad product. I think a cheap KMART diffuser would been a better purchase which would be 10 times cheaper and would not mind putting it in the bin if it did not work well.
