I love this diffuser! I already own the neom diffuser Which I use downstairs but wanted another for my bedroom and feared my husband may divorce me if I bought another neom one for £100, this was half the cost and I would say the quality is better and it is just as effective as my neom one. I use the neom oils in it. Not really a big fan of the changing lights but you can turn them off or set them so they stick on just one colour. Cannot recommend enough!
