The device beeps regularly every 10 seconds or so! This makes it really annoying if you are to use it in quiet places. Not only for yourself but for others around you too. Apart from that, it seems to be doing the job as you can smell the ions coming out.

The customer service from this company is very good.
The item is currently being shipped over and will leave a detailed review of the item once I get it! I definitely recommend getting this as the customer service for it is very, very helpful and understanding.
It definitely works. If you put it under glass and fill the glass with cigarette smoke it clears. I tried it. You can also see sun motes disappear / cling together and fall to the ground if you are around them. It works. It also is a bit shocking, meaning it literally shocks you if you touch the tip. But so does any ionizer.

I like to wear this in large crowds such as concerts. Just know that it does constantly make a beeping noise. In loud settings the beeping gets drowned out but if you were in a library per se you could hear it. I also do wish it was a little smaller

I wear daily to help keep my sinus from getting congested. It has helped me tremendously from suffering during this summer time. I just hate the bully thickness.

There’s been times I’ve not had my mask on and someone creeps into my space. My stress level is reduced knowing I wasn’t completely unprotected until I had time to put my mask on. Peace of mind and knowing I’m doing all I can is worth the purchase for me.

I had an issue with the first order, but it was resolved immediately. The unit works perfectly and even came early!
It is completely silent.Great customer service.

First off, I waited for this order for over 2 months, which when I get to use it and wanted to return the product, the return date already expired. Second, the beeping sound is annoying to a point that I don’t even want to use it. If you are not sensitive to beeping sound, then this product is for you. I have not doubt that this product is doing it’s job as negative ionizer, as you can smell “iron rusty” coming from it.

I can’t smell any ozone near it or even after leaving this thing locked in a small box for several hours. I regret purchasing this.

It definitely works! In a small space I get a tiny wiff of ozone, letting me know it is doing a great job. Long battery life.
Once in a while when you adjust the device you can feel a little prickly energy in the strings.
