I can breathe again

Love the device. Mainly in the bedroom, and as a chronic hay fever sufferer, I can now sleep and breathe freely without medication. Love the unit

Lovely Little diffuser

I've been using this diffuser everyday! It's easy to use and works well! I love the alarm clock function, lights and fine mist that disperses the essential oils. It certainly helps to create a relaxing environment and lovely air quality! Fast delivery too! Thanks Andatech!

Love it 😊 don't go past

These are the best, yes they are plastic but don't look cheap. They work spreading the sense to a large area. Look beautiful in a room and work so well. I've waited 6 months till I wanted to rate it so take my review as my truth 😉 the changing lights are pretty and option of on or off! I have two and use them each day! They are just no fuss you get just as it says! Love

Perfect form kids bedroom

Put it on for a couple of hours each evening and very happy with it so far.

Great product!

It is easy to use, very quiet and definitely refreshes environments like our lounge room even when we have all windows closed (as it is extremely hot outside!), and people come over and comments on how the air seems 'light', fresh and smell great. Excellent - would recommend

Very quiet

My wife loves this diffuser because it's so quiet. I have yet to work out all the options but so far it's a winner.

Great little diffuser

I love this little diffuser, it is very smart and modern, heats up really quick and dispurses quickly. The clock and the lights are also really cool.

Beautiful product, works well

I received the Ionmax Serene as a bonus for buying the ION420 Air Purifier. The two products work well together. The only suggestion I have for the Serene would be the ability to turn all of the lights off - I usually set it to run for 30 minutes after I go to bed. The machine turns off, but the light from the numbers screen is still bright enough to be distracting, and my partner gets up and unplugs it. Actually the ability to turn off the loud beep when you plug it in would also be good (means I can't plug in/turn on again in the night without alerting the world). But thanks!! Good products.
