Worked fine for me but I think the motor can stand out in really quiet meetings, maybe depends how close you are. Battery could be better though, I end up charging every few days.
Yep been using mine on bike rides, chest mount gives way steadier footage than helmet or bar. Tighten the strap so it sits snug and angle it slightly down toward the front wheel. Turn on any in-camera stabilization and keep a spare battery like you already do.
Phone UV box is usually less faff — agreed. I’m skeptical most cheap desk lamps actually deliver the dose needed, a high‑output unit or box is where you see measurable drops. Expect slow plastic/finish degradation with repeated use.
