Works great but doesn’t hold a battery charge and I have to keep it plugged in. I charged it for 6 hrs like the instructions said…. It only stays charged for a couple hours of use before you have to plug it back in. Also instruction book says there is an app and to scan the QR code that comes with it to download the app… QR code doesn’t direct you to the app download.

What I don’t like is when I turn the Scentiment off, it’s very difficult for it to turn back on. I do like that it doesn’t require water and even when it runs 24 hrs (because I worry about turning it off), it doesn’t require alot of attention.

I have had a diffuser with this technology before, but it constantly had issues with pressure in the container and would stop dispersing oil. This diffuser is clearly quality and I doubt I will have issues like that. I found the lights weird at first, but the more I use it, the more I appreciate them. The container for oil is rather large so it felt weird pouring my sample size in there. The mouth is not wide enough for it to screw on directly. I don't want to have to commit to a scent that way, but considering it's sample sizes and I'm testing the fragrances, I'll suck it up. The diffuser is sleek and unobtrustive. The scent disbursement is excellent even on the lower settings, which I appreciate. Overall I am happy with the quality and design of the diffuser.
