[This review was collected as part of a promotion.] As soon as I got the product, it was a very easy set up to connect to my phone and the instructions were very clear and it didn't take long for the device to work. The buttons on the product were also easy to understand and work with and the phone can easily change the settings in no time when you aren't near it. I can feel a difference from before using the product and after, it feels more fresh and I know it's much more cleaner thanks to the product. The sleep mode is very beneficial too, you wouldn't even notice it's there, there's no sound at all. This can be most useful in the summer as there will be a lot of allergens and all year round there will be dust too. So I would highly recommend this product
