Review: Works with DoorBird - I purchased these to create an easy way to unlock a DoorBird door system. Worked flawlessly. I am still trying to figure out where I can stick it on an iPhone case where it doesn’t get interference from the phone. But spots exist, you just have to be careful about where you stick it. Bottom line, works very well for my purposes.
