Review: Awesome product - I love this. It really smells up the area. I wish it had a way to set a timer like the smaller ones. I chose this because of the size, which is what I need for my upstairs. I tried putting a timer on the plug, but it will not auto turn itself on. But it does auto shut off, which is also great. But I would love to wake up to a nice smell.
Review: UPDATE! Don't not buy!!!! - OK so I had to come back on and give another review after a couple months of sitting in my closet I decided to take them out and try again idk how but they actually started working properly and it has been months of constant use without any problems! Just make sure you clean them out regularly I learned this the hard way the top piece that comes off/ where the smoke blows out has developed calcium buildup (best way I can describe it) which has stopped the smoke from blowing out correctly and they don't sell replacement pieces but totally not the companies fault! Great product once u get it working and customer service is GREAT when I had my issues they refunded me with no problem quickly. Literally had this product for 4 days already stopped working. Yes it's nice and big Yes the concept is amazing durability is an absolute zero. Save yourself the headache bad product overall!!!

### ⭐ Do not waste your time
*by A***R on June 30, 2026*

I purchased one of these humidifier for my home and it didn't work straight out of the box. (seemed to have zero power going to it) Wouldn't turn on. Was sent a replacement and this one leaks profusely from the plastic base as soon as water is added. So now I have two defective items to return for a refund. A waste of time energy and money. Do not purchase.
