Review: Brilliantly Designed and Incredibly Handy! - I recently added the SMALLRIG HawkLock H21 Universal Quick Release to my gear setup, and I'm seriously impressed. The build quality is excellent – solid metal construction that feels durable and reliable. It clicks into place with confidence, and the release mechanism is smooth yet secure. What I love most is how much time it saves when switching between accessories or setups. It’s incredibly convenient, especially during shoots when speed and efficiency matter. There’s no fiddling around – just snap it in, and you’re good to go. It’s a simple tool, but it makes a huge difference to the workflow. Definitely worth the investment for any videographer or photographer looking for a fast and reliable quick release system.
Review: Compact, Reliable – SMALLRIG Nails It Again - The SMALLRIG HawkLock H21 does exactly what it says on the box. It’s small, compact, and works flawlessly—exactly what you need from a quick release system. I’ve tried a few others, and this is by far the best one I’ve used so far. Solid build, no fuss, and super reliable. Honestly, SMALLRIG just always gets it right. Can’t recommend this enough if you’re looking for a no-compromise quick release solution.
