✅ Pros & Use‑Cases
Very small & lightweight clamp, handy for attaching small reflectors, bounce cards, diffusion material, etc.
Quick to use (spring‑loaded) for fast setups.
Because of polyvinyl‑coated tips/handles, it’s less likely to scratch delicate surfaces.
Non‑reflective black is good for photo/video setups where you don’t want glare.
Lifetime warranty gives peace of mind.

⚠️ What to Watch Out For / Limitations
Though rated ~8.5 kg, in practice the leverage / shape of what you clamp and how far from support matters; heavy items or long arms can stress the clamp or cause slipping.
Spring clamps can lose tension over very long use; check spring condition.
If using the ¼‑20 thread holes (for mounting small accessories), ensure you have the correct nuts/hardware.
Very compact size — if you need to clamp thicker things (boards, larger reflectors, fabric bundles etc.), you might need the 2″ version.
