for the price, this is great
quite satisfactory as a medical patch, which is why i've bought several....they're easy to lose/mislay
only downside is that the elastic can pull out quite easily, after less than a week >>> best way to deal with this is, immediately, simply pull elastic free, take something like a baking skewer (ideal), poke a hole through the patch, use the skewer to shove elastic_end through, tie it in a figure-of-eight knot > then repeat for the other side
apart from that, great >>> definitely terrific value
