Quick update, test that last "delayed one" strap extender and it's squarely in the decent category. Hooks easily and is thinner than the others. I don't love the elasticness of it (I find the elastics are what cause the cutting in discomfort but it's very mild with this extender). Also I wish one of the hooks could lock on for easier reuse, but given that these go on supposedly disposable masks I get why it's not there... For the most part it gets the job done. Favorites are still the "other x-back" and the "almost Ojai"...
