Great Little Humidifier
I purchased this little guy to go into my humidor that holds about 150 cigars. Set up and installation were a breeze. One word of warning; if you have a 5ghz network or mesh system, the wi-fi app will NOT work. It only works on 2.4ghz systems. Outside of that not working out for me, the humidifier has worked like a champ and keeps my cigars nice and comfy at 69-70% humidity consistently. I've had to fill it about every three to four weeks, which is awesome. Not having to worry about watching humidity and knowing that my cigars are at the perfect temp and humidity is terrific. I highly recommend this product if you're in the market for a humidification device.

It works!!!
Great product. Holds the humidity at the set point within a 300 cigar electric humidor. Calibrated using a Govee Thermo hydrometer.

It's a Must
This is a must for any cigar smoker. No fiddling with hydrometers manually and no humidity packs to worry about. The only downfall is the app which should be free, 1. Costing a subscription and 2. Not working well at all. But the device itself is money for keeping cigars at perfect rh 24/7.

Just buy it!!!
Straightened out my humidity issues overnight. The Boveda packs are great and all but this is a must for anything greater than a 50 cigar collection.

Perfect for that cigar smoker in your life!
I am new at the whole cigar fad. I’ve smoked cigars and have had a 25 cigar humidor that basically dried out a lot of the cigars. I’ve got a new humidor on order that should be here next week but I put this item in that 25 cigar humidor and I love it. You can smell the fragrance of each cigar and they are all perfect. The cord coming out is flat so the box can close completely. I’ve had one of these now for over a week and I just ordered another one. I would say this is a perfect gift for your favorite cigar smoker that doesn’t have something like this because this is literally a plug and play unit. I have upgraded to an 80 to 100 cigar humidor which this will still work perfectly in. I am keeping my original one in my smaller humidor so I can take with me on the road. I advise you get one of these it is awesome. There is a Bluetooth aspect but really unnecessary and not worth the cost. Smoke well my friends!

Expensive with low quality build.
This was my 2nd Cigar Oasis humidifier and the 2nd to totally crap out in 2 years. This unit was lower quality materials than the 1st. Also the water reservoir lasted less time. 1st unit would go 6 weeks in a hundred cigar humidor typically. the 2nd unit did good for water to last 4 weeks. At this price point one would expect more solid construction and for a unit to last longer than 2 years. That said, it did it's job and kept the humidor at the desired level of humidity for the 2 years it operated. No complaints there. So if $170 isn't too much every 2 years I guess it's for you. Not so for me. Won't be a 3rd one in my future. Never mind the (IMHO) useless subscription required WiFi monitoring. Likely a big contributor to it's outlandish price and build quality.

Does none of the features it's designed to do
This Cigar Oasis Ultra 3.0 gets mixed reviews, either 5 or 1 star. I assumed I could overcome the issues the 1 stars reported. I was wrong, just stick with Boveda packs, and get the Boveda Butler if you want to monitor your humidor on your phone. I used the Cigar Oasis for a couple months hoping it would work since I spent so much on it. The app never worked, its very poorly designed and they even say they are still working on it on their website, so you're paying to beta test for them. The temperature measure was apparently random, sometimes high, sometimes low, never accurate. The worst part was the humidity though. This is the main feature of this box and it fails miserably. It was high by about 10% so I would compensate with the setting, they it would correct itself after a few days and I'd have low humidity. The worst was when I went away for the weekend and came home to the thing running the fan at full blast with the humidity reading at 98%. It's own sensor said 98%, why wouldn't it stop the fan. This ruined some of my nice cigars. I took it out and went back to Boveda packs. Do yourself a favor and use the money you'd spend on this for more cigars instead.

Set it and forget it! Absolutely LOVE this high-tech humidifier
I've had this humidifier running in my 120 ct. humidor for the past week and it's been fantastic. Pros: - The WiFi set up was super easy (just make sure you know if your router uses WEP or WPA) - I love having the app with live data and alerts. - I have the humidifier set to 70% and its always within .5%-1% when I first open the box. - Super quiet operation. - Great design that allows me to mount it on the lid, which obviously saves space in the box for more cigars. - Set it and forget it reliable humidity control for my cigars Cons: - After setting up WiFi and installing the app I was surprised with "free 30-day free trial" -- does this mean I'm going to be charged to use the app? How much? How often? This is something that, if Cigar Oasis, is going to do (and I'm not really sure they should be) then they should be more transparent about the pricing, etc. Can't find anything in the app or on their website about subscription cost. - The ribbon cable is a great innovation but the cable that shipped with my unit has a thicker connector on both ends that doesn't slip through the back of my humidor. I had to remove one of the brackets on the humidor lid to slip it under. Not the end of the world, but an extra step that would've been unnecessary had they not changed the cord design. Overall, this is an excellent product and I'm very pleased with the build quality and support. I look forward to using it for many years. I'll be sure to update my review as time goes on.
