這個產品非常好用,我經常戶外活動,蚊子非常多,有咗佢可以防蚊又有照明功能,萬一天色昏暗都可以用得着,我會繼續支持貴公司的產品,謝謝
You cannot use the app Sleeplus in the link of the user manual. The link needs to be updated on the user manual; However, you can look for the app named VVFLY YA50 on a web browser. I have an iPhone and with the VVFLY YA50 app, I can pair it onto my iPhone.
One thing, though. The machine itself is quiet; The mask is a bit noisy but acceptable.
