"I am using Birdie in our class room. From day one you could easily feel the difference. Opening a window is easy enough, but nobody does it. With Birdie it's never gonna be a problem anymore."

Tseard from Denmark 🇩🇰

"As an owner of an advanced CO2 monitor, I've always struggled with explaining what the numbers meant. Birdie comes to leave that behind and have a visual experience. It has changed my house's dynamic; we never want to see the bird down, so we air the house a lot more."

Beatriz from the United States 🇺🇸

"My bird has been sitting on my wall for over an year now. It's pretty stylish and complements our decor well. Also, I've only ever charged it once. It lasts surprisingly long."

Itay from the Belgium 🇧🇪

"I never realized when was the right time to ventilate, and I was surprised how often one sits at home with poor air. It's somehow even fun to take care of Birdie so that he's always up. Since then, I've also had a lot fewer headaches..."

Grazia from Germany 🇩🇪

"Amazing how such little Birdie can be more efficient in “forcing” you to open your window and let in some fresh air than any CO2 meter with whatever function. As I’m typing this review she is turning downside so I have to go to open my window NOW 😊"

Dániel from Hungary 🇭🇺

"... I also love the subtle historical context behind the design alluding to birds in coal mines. Birdie brings me great peace of mind and even entertainment. Every time she drops- I gasp. and always feel better when she’s upright again."

"Is it working? YES!

Since my Birdie is working so well, I decided to gift my two sons with a Birdie. It makes a great Christmas gift!"

Darling from Denmark 🇩🇰

Great little pet

"My kids are especially fond of their new pet. We are venting more than before, so I must say that it's true to it's word."

Marie from United Kingdom 🇬🇧


"It's made such a difference to keeping on top of making sure my house is always filled with fresh air :D"

Andreas from Switzerland 🇨🇭

It is really as simple as expected

Once birdie is mounted on the wall it works. And it's really simple. No APP, no LED. A lot of motivation to open the windows more often.
