This strap is pretty comfortable; the wider part of the band helps distribute the weight and the central section is also padded; meanwhile the ends are narrower to help reduce the bulk around the camera and keep weight down a bit more. The overall usability is pretty great, and the clips have an extra security button to prevent accidental opening. Note that the clips and thus the "anchors" are compatible with K&F's other similar lineup, such as the hand strap.

That said, despite the anchors being pretty solid, they are a bit bulky so that can be a bit of an annoyance during use, especially when all straps are removed from the camera.

But for me, the biggest usability flaw is probably the fact that I find this strap a bit too long for many uses. I do appreciate being able to lengthen it sometimes but you do run into problems trying to shorten it for a safer carry. The narrower part of the straps make it fully incompatible with the adjustment system, so that's almost half of the length being unusable in adjustments. Ideally I think that the narrower section could have been 1/3 the current length. Then there is also the fact that the center of the wider section being padded. Thankfully, unlike Peak Design's Slide, the padding isn't so thick that you can't feed it through the buckles, but it takes a lot more effort to do it and means that you cannot lengthen nor shorten it while wearing it as the padding makes it impossible to slide through the buckles freely.

So if you need a very long strap, this could be a great option. But despite the overall decent build, I find the length adjustments to be too limiting for my own personal use as my main strap.
