Waterless Essential Oil Diffuser for Home 8 Working Times and 7 Spraying Times to Choose from Mini Cordless Battery Operated Aromatherapy Diffuser for Room Cars Office(White)

As it was famously sung: “Simply the Best!”
I don’t know what sorcery this is, but my biggest complaint about fragrance diffusers has been completely obliterated with this amazing gadget: there’s no water involved. No water to get scummy and gross while it sits unused, no water to try to balance with the oils (which of course always separate, making the diffusion unbalanced). Just oil and…presto!I’d had this for a few weeks, and used it nearly daily for several hours. The original 10mL bottle of oil I put onto it is still about 3/4 full, AND the diffuser is still running on its initial charge (via included USB-C cord, which is great). It looks great, feels substantial and sturdy, and wait till I tell you about the BRILLIANT button design!It does come with an empty bottle for you to fill straight away (however, it would be nice if they’d include a cap for it, because the threads/cap size won’t necessarily match what you may have already). They also include a bottle of lavender oil, which I immediately dumped and rinsed because I don’t want my house to smell like geriatric perfume. At least there’s a cap on THAT one!The manufacturers have thoughtfully included a couple of replacement parts and a cleaning tool (though I hope not to need that stuff!).Now, the buttons. They’re well-marked and have nice, bright white LED lights that are easy to read. The POWER button obviously turns it on, and it begins diffusing the oil immediately, without any wait/warmup time. Next, there’s a TIMER button, which cycles through four settings (in various combinations) with each tap: ON, 1, 2, and 4. If you set it to “ON,” it’ll stay on until it runs out of oil and/or charge. Otherwise, if you tap to illuminate “1,” it’ll go for an hour. Tap again for “2,” and it’ll go for two hours. Tap again and BOTH “1” and “2” light up…add ‘em together and, that’s right, it’ll go for three hours. Tap again and you get “4.” Again, 4+1= 5. Again, 4+2=6. One more time, and all three numbers (1, 2 and 4) are illuminated, meaning it’ll go for SEVEN hours! Pretty genius in its simplicity.The ”ON INT” and “OFF INT” buttons work the same way, except they’re increments of 10 seconds: 10, 20, and 40: rotate though 10, 20, 30 (10 and 20), 40, 50 (10 and 40)…you get the idea. The “ON INT” is how many seconds the fragrance diffuses its glorious microfine mist (nope, no residues or “overspray” on any surrounding areas!). The “OFF INT” is how many seconds in between those misting intervals. This lets you customize the strength of the fragrance to your environment. (I’ve settled on 10 seconds ON, and 70 seconds OFF, so the “ON INT” is set on 10, and the “OFF INT” is set with all three on (10, 20 and 40).I reached out to the manufacturer about the size/threads of the bottles used, and they shared that the bottle’s mouth exterior diameter is about 17.40 to 17.90mm, and the threads have a pitch of 3.2mm. Ummm…OK…but they also provided a link to bottles that would fit, which I hope is OK to share here: https://a.co/d/50jvl7V.Pro Tip: I used my labelmaker to indicate which scent is in each of my little 10mL bottles, and have several of them in a cabinet near the diffuser. This way, it’s super-simple to swap them out when I want to change the fragrance. (In this case, I typically run the diffuser for a good 70 seconds to get all of the previous scent’s oil out of the tube, and yeah, they briefly mix/mingle, but it’s short-lived…and if you’re really bothered by them doing so, just hold it out the window!)Thanks for reading; I hope that my review helps you out!
