Great for office privacy
We have a small house and my partner and I work in adjacent offices with a shared wall. This sound devise sits outside both of our offices in the hallway in between our doors. With both our office doors closed, it's just enough noise that we can no longer hear one another's conversations on the phone with clients through the wall. You can kind of hear mumbling, but you can't make out any of the words anymore. The devise sounds just like a fan. As much as we don't love the &#34;noise pollution,&#34; it's a small compromise to help us maintain privacy and stay focused on our own work when the other is talking to someone. Definitely easy, portable, and reliable. My only complaint is the price - for such a simple devise, it seems like it should cost less. That's my only complaint and why I docked a star. But otherwise, I really couldn't work as productively without it (or I'd have to find some other devise that did the same thing). If you're looking to solve a similar problem of noise bleeding into adjacent spaces, I would recommend this devise without hesitation.
