So after starting with a helmet that had one of these built in and then going to the original strap on my new helmet I started to miss the ease and convenience of being able to unstrap my helmet even with gloves on.
So when I saw thus and I didn't have to remove my current strap setup, my only thought was "is this gonna make the strap too long?" The sales guy confirmed it wouldn't and even installed it for me. That next ride with that and every one since has been so much easier because of this connection.
In my personal opinion, the like the original strap idea, but this needs to be made available on every helmet as a built in feature. There's just something satisfying and reassuring about hearing that click as it locks into place.
