Firstly, their product is amazing. I got my first birdie in the beginning of 2023 and I fell in love with it. My birdie hangs in my bedroom/study and always helps me open up my windows. With my high ceiling, that is about once/twice every day. The battery lasts months. Not sure how long specifically since I took my birdie off the wall before I left for a long vacation.
Secondly, their service is great. A couple months ago, I ordered a blue birdie for in another room. I wanted to use a discount code I received with my first birdie, but the code didn't work. They kindly replied to my email and gave me a personal code I could use to apply the discount.
Thirdly, the design is great and so simple. Before I got my second birdie, I was thinking about getting an elaborate co2 meter. However, the more I looked into it, the more I realised why I bought my birdie in the first place: it's such a nice product to look at, and more importantly, I can instantly see if my air quality is okay.
Lastly, I think it's also a good pick price wise, even though they aren't cheap, they are sold at a competitive price.
I love my birdies, it's like having a pet buddy without the cleanup.😝
