Perfect, or almost, sums it up.
I had received a personal steamer last week that I gave 1star and got rid of. Ordered this unit in the hopes it was close to the description. Exceeds my expectations. Easy to hold. Fits wonderfully well and you get to inhale almost all of the steam. Love the carry bag that comes with it. Even holds a bottle of distilled water so you are good to go. If you have sinus issues or asthma check with your doctor but I believe this will help.

Sadly no good
Wanted to like this as they make a great humidifier. I’ve had two My Puremist versions so I had expectations. Very little steam and intermittent. Kept running on and off and made a lot of noise. Felt cheaply made and rattled out of the box. The mask was hard to get on, didn’t seem to seat properly when it did and broke when I removed it to pack up for return. Used it twice but that was enough. I see that you can buy the original My Puremist and although I expect it not to last much more than a year if that, I will get another one as when it works it’s great.

Error shutdown
I've had it for 6 years and have had the same blinking green light problem. What has worked for Me is to reach my little finger down into the water reservoir and rub the little brass sensor at the bottom (seems to develop a film) dump the water and start over with fresh distilled water. It's frustrating, but seems to work.

Convenient
I like that I can use water from my own distiller rather than having to purchase it although one gallon of distilled water would probably last all winter if used only once daily. I don't have any sinus issues but it just feels good in the drier winter air. I use it while watching TV sitting in my recliner.

Not enough capacity for steaming. Mask too difficult to attach reliably.
We got this unit as an alternative to the standard Vicks product which we have used for allergies for years. Unfortunately, when we tried the unit the mask was very difficult to attach, the unit holds too little water to be effective, and after filling it with distilled and filtered water, the unit simply didn't work. We returned it with a couple of other items in the same box, but haven't received a refund.

Confusing product
My allergies and sinuses are always bothering me. I sneeze often, blow my nose, clearing my throat and many times can’t sleep because of it. I purchased this so I can have it on my nightstand for the middle of the night episodes. The mask was very difficult to put on. Took a lot of effort to snap it together. Once I got it together, I added bottled water. I didn’t realize distilled water was a whole different type of water. It absolutely will not work unless you have distilled water, so get distilled water. I finally got the distilled water and you only need about an ounce if water to run it. You have to use it sitting up, otherwise the water drips out and it stops working. I let it run for a couple of minutes before using for the steam to warm up. I put the mask to my face and it starts working well then the steam gets cold for about a minute and then it gets warm again. I don’t know if it’s supposed to do this, but I don’t like it and it doesn’t help my sinuses at all. The product does help when the steam is warm, but isn’t easy to use and not very comfortable. The adult mask is also a little too big.

Burning plastic smell
Unfortunately this was a dud. I read the manual and I let ran it run 5 minutes with distilled water to clean/ sterilize before I used it and I noticed a bad smell like burning plastic I didn’t think something like this would have a burn off smell. Since then I used it twice today with the mask on and the smell was still there SO strong.. this is a product your customers put on our faces and breathing in this smell so this is not okay. I’m really dissatisfied and currently can’t recommend this especially not for the price. It also has a prop 65 warning and while that can be for something that you won’t be breathing in it’s still unsettling to see on a product like this.

Warm mister
This warm steam mister is just the best, it keeps my nasal passages and throat moist and clear.
