It cannot be stable enough. I have other mini tripod selfie sticks and they're great for portability and OK if not extended. But pulled out, forget it.
@@Gemini_Connectthanks for answering. It is what I was thinking. I have Manfrotto tripod, seems to be very thin, but still, heavy. When walking with it in a backpack and some water in a bottle i becomes heavy. I am looking for something more compact. Carbon fibre thing would be good, but not easy to find yet.
I have that tripod and traded it in for one that was more versatile and could hold a phone & a camera. And the new one only cost $10. The one she's demonstrating is way overpriced.
