Review (4/5): Works as described with only minor concern..
So these certainlty work. The reason I gave them 4 stars vs 5 is that while using them in constantly concerned I'm going to choke on them. I don't know if there's a way to have them be connected but free floating, as they are, makes me leery. They work like they're supposed to & I've seen definite change in my has profile from regular use. I do recommend them, I simply can't get over the concern of it being a choking hazard.
