My second one! After about 8 years, my last one started to just put out a minor amount of vapor ( I think I caused it's demise by a too rigorous cleaning.) so because I've been so pleased with it I bought another. 8+ years is a long time for anything these days and I run mine all the time. I particularly love this one because it connects to Alexa and by doing so I get voice control (turn off/on, vapor on high/low, different light colors etc.) and by being on Alexa I can also run it with a schedule. It has a great water capacity, is whisper quiet, and shuts off when the water runs out. Looks good too!

How to Connect the Smart Diffuser to Alexa (Step-by-Step): 1. Download the “Tuya Smart” app (or Smart Life – either works the same) from your phone’s app store. Look for the logo with a white "T" on an orange background. 2. Plug in your diffuser and make sure it’s flashing or in pairing mode. (If it’s not flashing, hold the power button for about 5 seconds to reset it.) 3. Open the Tuya Smart app and create an account (or sign in if you already have one). 4. Tap the '+' button in the app to add a new device. Choose Small Home Appliances > Diffuser or Humidifier (Wi-Fi). 5. Connect to your Wi-Fi (must be 2.4 GHz) and follow the prompts to pair your diffuser. 6. Once it’s added, tap the settings in the Tuya app and link it to Alexa: Go to your Alexa app (already on your phone), Tap “More” > “Skills & Games” > Search “Tuya Smart”, Tap “Enable to Use” and sign in with your Tuya login to link the accounts. 7. Alexa will now discover the diffuser automatically. You can say: ➤ “Alexa, turn on my diffuser.” ➤ “Alexa, set diffuser to high.” (if it supports settings) ➤ “Alexa, turn off diffuser.” --- 🌟 My Honest Review: I absolutely love this smart diffuser! Setup was super simple once I downloaded the Tuya Smart app (that’s the one with the “T” logo). I connected it to my Alexa app on my phone with no problem. Just a couple of taps and I was able to control it hands-free. Now I can say “Alexa, turn on the diffuser,” and boom—it fills the room with the most amazing scent. I personally use Pure Essentials oils from Natural Grocers—they smell clean, fresh, and not overpowering. For me, that’s the best scent combo and where I love to shop for my oils. If you're looking for something easy, affordable, and smells amazing, I highly recommend this diffuser. It works like a charm and makes my space feel like a spa with just my voice.

This is a really neat little oil diffuser. The 2 settings of volume, weak or strong really work well. What doesn't work well is the software. Any settings of timer on/off (2 hr, 3 hrs etc)in the timer section do not carry over to the schedule section. There you have to enter a start time and then enter a stop time. Took me a while to figure out why it didn't't shut off after my 3 hour timer setting The manual, well the manual is good for a coaster. But when you figure it all out it really is a cool device. Came close to returning it in the beginning but am glad I did not. If you get really frustrated I would answer questions and I am sure others would too.

Stylish and functional are two words I would use to describe this product. Easy to use straight from the box without the Wifi set up. I have not tried that feature yet. I like that it cuts itself off when empty, but it does a hold a lot of water and runs for hours. The oil scent stays pretty strong for a long time. It doubles as a humidifier so it can be used without oil, also. The led lights can run without the humidifer/diffusing feature going so I use that as a nightlight sometimes. It does turn off the led lights once it is empty if you had the diffuser going at the same time. I have found that placing it a corner, table height, in an area of the room where air flows pulls the scent through ventilation is best. Don't place it right under a ceiling fan but off to the side of the room and let the ventilation from the fan gently pull the scent across the room, as a suggestion. Depending on quality of oil you use, it can overpower small bedrooms but it can be overwhelmed in larger open floorplans, depending on cross ventilation. It has a low and high setting so you may have to play with settings that best fit your area to get a desired experience. I have 4 of these in my 3 bedroom, 1530 sq ft home and I have bought two as gifts. I do not have an open floor plan (Cape Cod) so I placed 2 downstairs and 2 upstairs. The picture is of the one in the downstairs bedroom.

It's easy to use and works great, giving nice scent to a larger than expected area. So, why three stars? I got this one for it's looks, as opposed to other, cheaper, plainer ones that would more than likely perform the same. Loved the idea of diffusing sandlewood and patchouli in a unit that looks like something one might find in a dimly lit hippy head shop back in the day. Also, I have used it carefully, followed instructions, and kept it clean. Only distilled water is used for diffusing and only heavily diluted mild dish soap, soft cloths, and cotton swabs for cleaning. I cared for and loved this diffuser... Until today. 4 weeks in and there is significant cracking/lifting appearing in the finish. This will, no doubt, quickly lead to peeling, making what was once pretty, pretty ugly. :( What could be causing this?? The cracking has started on the top piece, very near the bottom where it rests against the base. Perhaps this area gets warm... Perhaps it's this area that is always nearest to the internal diffusing unit, as the base and lid are always oriented the same... Maybe there is some leakage here as it bubbles near the edge. I have noticed mist accumulation a time or two but cleaned it off and didn't think much more of it. If this is a problem, why couldn't the diffusing piece be central? And why would a product marketed for diffusing oils and water be manufactured using a finish that becomes damaged when exposed to those very oils? I am no engineer, but dear Reader, I have been careful and can find no reason for the issue other than poor design. So, I implore you to give this some thought if looks are important to you. Am I still using it? Yes, right now in fact. Will I continue to do so in my pretty new home when it starts to really look like junk? NO! As a reminder, this may not look so bad now, but I am only 4 weeks in, and it's bound to worsen sooner than later. Edit: 05/10/22 A year later and I'm back to say that the damage did get worse, despite careful use. It's UGLY and I'm on the hunt for a better made diffuser... But also, it's still working. Diffusing some sweet Nag Champa now (with the ugly unit hidden away, out of sight, in the bedroom.)

The device itself works GREAT. I mean, blows away my other diffusers. The wifi and app, not so much (but will "work"). This pumps out quite a stream. My house fills with scent (farther) and in short time (faster) than all my other diffusers. Oil is going to go a long way here. Short story, i'll get another one of these for my basement and give away my other diffusers, Using less oil will pay for itself Setting this up is terrible though. I had to call their support and i/m an IT expert. Don't despair, here's what you need to know. - the instructions and the app don't match. It appears that the app is updated after product is packaged. - app is made by a 3rd party company that has no idea about the device. This all starts to make sense. - You need to download app, setup account, then go into add device ("+ sign in top right corner). This is in the instructions - whats not in the instructions is that you need to scroll alll the way to the bottom category, select "other" then select "other wifi devices" from the list, then it will go into a pairing mode. - there are two modes, they dont explain what they are. They actually use wrong terminology. - when you go into pairing, right button on device contorls on/off and wifi modes. slow pulse is "manual model". Fast is other mode. Long presss to toggle between them. Try and use fast pulse, it sans network and if unsuccessful you can choose the other mode that will let you manually find and connect to it. FYI, wifi pairing details (these details) arent in the manual. The wifi app is basic. For every schedule routine you setup (turn on at "x" time), you need to create another routine to turn it off (or stays on indefinitely). Why they dont just have a feature that lets you say "turn off after 5 minutes" is beyond me. Also, the buttons to make selections in setting up routines are terrible...you'll see. The good part of the app is if you want to just contorl it in real time (now), those buttons and controls are really good. So thankfully, i dont think i will be spending as much time scheduling things in the app as i might ad hoc (because i'll set a schedule and likely leave it). Last, it asks for permissions to bluetooth and location. This device pairs via wifi, so i cant imagine why it needs access to bluetoth (it doesn't since i didn't grant access). Also, same for location services. I imagine because the app is made by a third party that connects to what seems like hundreds of potential devices that may have these functions, it asks anyhow. You can say no, it will work. It appears to work with google home (the app), so perhaps this is where location services might be useful if you are on that platform and wish to setup a routine. Outside of this, from a security standpoint, say "no". Change it later if you need to. I do recommend this device, hopefully this review helps people save some time and hassle - and developer takes more care with instructions they provide.
