Great device good customer service First off, great product, not perfect - but almost. A handy little air quality monitor that handily keeps an eye on the ambient conditions. Syncs well with the app, good clear information and hints within the app re the feedback from my sensor. Although the readings use a different system to AQI, its basically the inverse. Creates a good record of the pollutants and air quality issues faced indoors and while I'm out and about. Important when you have allergies and a respiratory condition. The unit has experienced a malfunction which requires it to be sent off, and whilst timezones mean email exchanges can be a little slow, customer service dealt with me efficiently and fairly. The clinch for this over say the plume 2 is battery life. Its far superior on the atmotube. A few online tests give the atmotube the slight edge in accuracy, although for me its the battery life that clinches it.

Terrible experience regarding my refund… Terrible experience regarding my refund (which I am still waiting for!) I shipped the unopened device back to atmotube within 14 days of orginally recieving the device using a tracked courier. The device arrived back to atmotube on the 7th of Feb and I have heard no response or email confirming this although I sent it tracked with a signature. I have sent numourous emails to them since and nobody has bothered to reply. There is no webchat or contact number to speak to anyone. Will be taking this up with trading standards shortly if I fail to get a response and refund!
