K&F Concept's products have impressed me for some time, and this strap is superbly crafted, from the professional, classy packaging to the strap itself. This wrist strap is designed for use with cameras, but can also be used with anything to which the loop of the lanyard can be attached. This strap consists of two parts and is connected to a plastic buckle with a safety clasp to prevent accidental opening of the buckle. The strap has a variable adjustment slider, which I think is very intuitive and allows you to remove your hand from the wrist strap when you want while still keeping the strap secure when you need to. I'm not sure why K&F went out of their way to inform you that there is a wear indicator in the strap that attaches to your camera. I have been using similar wrist straps for at least 20 years and they have never failed at the loop. It's nice that you get a wear indicator, but I'm also concerned that K&F isn't confident that this strap will be durable enough. At the time of this review, this bracelet costs $39.99 less a $10 coupon. The price after the voucher is reasonable, but $40 is too expensive.
