I like it too, but I have a few ??? in my head.
How easy is it for this thin piece of metal to bend? If it bends it bends big/visibly? or is it slightly deforming with every set and then one fine day you find yourself in a beautiful pre-release situation? How fast does that day come?
In other words, how robust is the product and how do we know it? How many people and for how long have tested it?
I read that the plastic part is 3D printed. Hmm, unless they have a kick ass super expensive printer the polymers used in 3D printing are not super durable.
Bottom line, I am sceptical liek I am with all new binding systems.
