Do you have children? I frequently want to record things my daughter does but I find that my phone is not close at hand. I am curious if the latency to record is low-enough and I don't want to distract my daughter while she's doing whatever she's doing. I just want to capture the moment for later without interrupting the moment. They advertise it as this but I am curious what it's like in actuality.

I use it all the time for this use case. It's great because your hands are free and you can remain an active participant in play/safety/feeding. I find I capture more moments that I'm more actively involved in vs passively holding the phone and framing the shot.

They are great just for that and many instances you want to quickly take a pic and not interupt a moment.
