So far I've ordered 3 sets. My son loves it and the school he attends requires him to wear masks at school. Instead of washing every day I now have 3 sets and can wash them once a week. Since the prices are constantly falling, it is worth buying later. The first set I bought a few months ago is still holding up well. The rubber ear hook is still stable. Will update this post once the ear loops on the first set come loose.
