>> One negative rating claimed that it only lasted 100 minutes.
I think he’s referring to the battery life, which is mentioned in the Q&A, not the overall life of the camera. Since it’s billed as a spy camera, having only 60-100 minutes of battery in a situation where plugging it into the wall would give away its location, I can see how this would be a problem. For Lego videos though, it’s not. I’m still tempted, I might order one. The big thing I noticed is that it requires a micro-SD card, and I don’t know anything about them or how much they cost.
