And yes the bike bags were at the very bottom of that pile of baggage and they survived without even a break disk bent I liked it very much, and I put it on urgently. It does not have enough space to hold a normal kid in high schools stuff. So instead of one uniform piece of material on the bottom it is in two pieces when I walk. I’ll update the review with what I find so anyone else with a half size will know if it’s better to size up, like the manufacturer suggests, or actually size down. She sent a replacement right away and I received those in three days. Description says 7 hrs but 5 is the max and then it gives a warning about 1second before shutdown. These are one of the best . IT WORKED! Theres no way theyre the same size if my foot cant even touch both ends while wearing.
