I ordered the Leofoto NF-05N to replace a Kirk LP-70 that would not attach securely to a Nikon Z 600mm f/6.3 lens. Kirk made me send the LP-70 back for them to "review" before they would consider sending a replacement, despite sending them a video of the problem (I'm still waiting for a response as of this writing). I needed a solution in the interim, so I purchased this Leofoto NF-05N replacement foot. I admit I didn't have high expectations initially but, frankly, I couldn't be happier with the product. The foot attaches solidly with minimal effort and does exactly what it is supposed to do. If and when Kirk replaces their defective foot with a new one, it will probably end up in a drawer.
Leofoto will definitely be my go-to in the future!
