As the title says, you can never have too many anchors. Keys, earbuds case, camera - they can be connected to pretty much everything to be used later down the line.
I still have my original pair on my main camera/strap for over 2 years and they still show no signs of wear. I purchased another 4 pack for my other cameras as well. Very pleased with Peak products!
I have a couple of cameras that I have these attached too and I absolutely love how easy it is to switch my straps and even just remove straps all together depending on what I'm shooting! The products are wonderfully designed and the build quality is unmatched compared to other companies.
