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 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!

I bought this a year ago and then suddenly it stopped working. I looked at recent reviews and can see so many people have had the same problem but Neal's yard seem to be doing nothing to put this right. They are obviously designed to only last a year. I will be complaining to Neal's yard about this but don't expect anything as they are fully aware of the problem. It has certainly put me off shopping there which is a shame as I have shopped there for years. Just another big Brand buying cheap products and selling them for a lot of money. Very foolish as they are damaging their Brand...

Don’t buy this !! Mine lasted 7 months and then stopped working and with research it seems this is a common problem . It’s an expensive diffuser and therefore not worth it . I took mine to the store hoping for an exchange but they told me as I no longer had the receipt they wouldn’t swap it! They even said you might not have bought it from here ... it’s got Neals Yard engraved on it ... where else would it have been from . Hopefully Neals Yard will see all the negative reviews on this item and discontinue it as it is unfair to allow people to purchase an item that clearly has design / manufacture issues...

Echoing many of the other reviews below, the mist function stopped working after a short time...
