Credit where it is due folks I've just had some excellent customer service from Recknagel. I use their QD sling swivels on my rifle and have found that I would occasionally have one fail. I took some pictures of the failure, I'm an engineer and so prone to thinking funny sometimes, and sent them to Recknagel for their information as the two that have failed on me have shown the same mode of failure. I figured that Recknagel get a good reputation for their engineering and quality and so they would want to, at some point, design to mitigate for this mode of failure.
They replied to say that the photos were now with their technical team and that they would send me two replacement swivels which I thought was a very nice gesture on their behalf as although the mode of failure was the same in both cases it could easily have been argued as a "wear and tear" failure, though the swivels have not been abused and I would say they have had a relatively easy life. The package arrived today and when I opened it it contained no less than 5 new swivels.
So, I know that Recknagel gear is not cheap but I have seen evidence that they are proud of their engineering and that they stand by their product with a view to keeping the customer happy even to the extent of over delivering on their promises. It is nice to be able to give praise where it is due. (Did I mention that you should never, ever, buy a Land Rover? )
