I bought the Ultra to use in an older Reed Barton/Diamond Crown 150 count humidor and I like it for the simplicity of use. I also use a digital hygro/therm and they are staying very consistent with readings. VERY quiet and I think will be more economical than the humidity packs and less maintenance than beads. I’m really happy with the set up!

Too much

It was fine while it worked. Now its just another collect ion item. Flat Wire came apart and too much to spend for another. I mean the wire just lays there.

17 year run

I'm in the market for a new Oasis humidifier. Last one lasted (best guess) 17 years. It has been flawless! So, of course I'm buying another! The added wifi is a winner in my book. The old version required you to pay attention to the fan running non-stop to know you had gone dry. I thought it would have burned out years ago, but the thing just would not quit ... until now. I hope the new ones are as robust!


Keeps my humidor humidified but the temp gauge is off and it doesn't alert me when it needs refilling. The app is a joke. Other than that it keeps the smokes moist.

Excellent Product & Support

The device works great and requires little maintenance. I had an issue with the online portal and customer service was very responsive and quickly worked to resolve the problem. Ditch the bovedas…
