Out of the box, the pen looked like it was well made. It's a little heavier, which gave me confidence that expensive cameras and accessories that I attach to it will fit. The NATO clamp had a well-designed quick-release mechanism that firmly connected to the included rail. What impressed me the most were the little lugs on opposite ends of the NATO rail that prevented the grip from slipping off the rail unintentionally. I was also able to attach my monitor and the Atomos lamp to the handle without any problems. After shooting this grip for 6 hours I can confidently recommend it to anyone looking for a grip!
