I absolutely love the diffuser!! It’s beautiful and it works perfectly. The app worked the very first time I opened it and hasn’t again. I am so sad about this, because I thought that it was such a cool feature.

My app works well. Have had device for three months and I use device and app multiple times a week. One thing I wanna point out about app... the Bluetooth button in grey at the top left corner of the app (in the main screen where you turn on and control mist and time settings) you have to click that and it takes u to another screen. I only had one option. Click Youngdo_Ble and it creates a check mark. The app works a whole lot better and faster when u do this. Hopefully this helps.

I got the diffuser about 6 months ago. It worked properly (although i never tried the alarm feature)for 2 months. Now the bluetooth is malfunctioning, my phone can’t connect to « Youngdo Music ». « youngdo ble » appears and shows it’s « connected » when it’s not. In short, the diffuser can’t play music or anything else anymore, only after 2 months usage. I feel like I lost my money!

The diffuser is great, however nothing functions in the app besides playing music which only has access to certain songs in the library. That’s fine, because you can play music directly from your phone on it.The color changing light function doesn’t work, changing the mist doesn’t work and the power doesn’t work.
