These have been around for a long time since I recall seeing them several years ago ("Pressy"?). Given that, I don't think they caught on because I haven't seen them discussed everywhere (at least I haven't). Do you know what this one actually does? Doesn't it need a companion app?
Yes, these have been around for quite a while. I think that the concept is absolutely outstanding and practical. It's simply a trigger that is connected to an app / software. The amount of functionality and usability you get from it is completely dependent on how you have it set up in what you have it triggering. For this price you can't go wrong.
