They are super functional because you can put 6 dish towels on one of them (9 if you really want to) and at the same time you can tuck it on the side of the cabinet and cant even see it. I have not yet put this Cargo Carrier into service. I work in a factory and can only have one bud in so I can hear my boss/lead and the forklift drivers; dealing with oily metal parts, and with gloves being really in-demand, I was unable to even realize the other still worked and stuck with absolutely no music for nearly 2 hours. The band isnt too wide either, which I read could be a problem with the adult sizes. At around $11, these are absolutely worth it! Like buying an Audi instead of a VW, or a Lexus instead of a Toyota, or an Infinity instead of a Nissan, you get the point. I typically wear a 7. I figured, hey, if the ZSNs sound that good for ~$20, the ZS10 Pros must be even better, right?Well, bear in mind that you get diminishing returns with this stuff as you go up in price, but I figured for $45, even if the ZS10s didn?t absolutely blow their cheaper brothers out of the water, at least I didn?t drop that much on them. The curved plastic piece sits inside the rubber base. The size chart doesn?t give any indication of this size difference.
