You’d think paying that much for a diffuser it would last for a while but it broke just after a year which is very disappointing. Not worth the money. 

I’ve had my Esta for 5 years now and use it virtually daily. I love the subtle drift of aromas around my studio and it sets the scene for whatever I’m doing. Just a big part of my ritual now.  I only use deionised water in it, the type for irons or batteries, never tap as we’ve really hard water. Perhaps that’s why mine has lasted so well and doesn’t smell like others have commented.

This is the second unit I have had. The first lasted just under two years, as has the second. The first unit stopped misting properly and, as the disc cannot be changed and I had been pleased with it up until that point, I decided to go for another. The second unit is now suddenly dispensing the unpleasant musty smell that other reviewers have commented on (despite careful maintenance). I will purchase a different product for a replacement

Looks the part but as everyone else points out it stops working. Better buying one from Tkmaxx as much cheaper and last longer ! Customer service passed the buck saying contact zen as they are the supplier! Bought by my sons for mother day last year paid cash boys don’t keep receipts! Bitterly dissatisfied. Assistant told me “I’ve had mine 4 years” that doesn’t help me. Poor show certainly won’t be buying oils from you anymore!

Bought one and not working after few times using it. Brought back to ask to exchange but it working at the shop. On and off not working and at the end just fed up and throw into bin. For the money I paid is really not worth it

I love my ESTA but how do I change the bulb, it no longer works?

This diffuser looks great and served me well for a couple of years before it completely stopped working. For so much money I'm shocked that it doesn't last and only has a 12 month warranty

This is an extremely disappointing product. Its not cheap at all but something I thought a worthy investment that I assumed would last me a long time. I bought it to have for the birth of my first child two years ago and have used it very seldomly only in winter mostly during cold and flu season. I just turned it on today and it diffuses for about 10 seconds and then turns itself off. It cost me £50 and now it's going to go into landfill, another bit of plastic waste! I'm very disappointed in Neals Yard over this product I would have expected better quality at such a price and from a company with its ethics

I bought this diffuser today. Used the product as instructed but suddenly it stopped working, turning both mister and lamp off. Water level was half full at the time and as I am new to this I thought, although unlikely that, it might be at the ‘sufficiently low’ water level so I topped it up with water. Restarted the product and after 1 min again it suddenly switched itself off. Having just read other reviews on here there must be some electronic issue with some lots of this product. I’ll try again tomorrow. If same issue persists then I will try get refund. Not happy

A year old and the on/off button stopped working suddenly. It was used intermittently. Just run out of warranty too, fleeced!
