we used all the displays that were good in the backup display shipment. i ordered more backup displays from 2 more suppliers now while the main/bulk display supplier is still letting us wait (we ordered and paid 12 months ago from them).
from the first backup display supplier, we got a box of 100 displays and 66 were broken. here are some pictures that show how broken the worst ones are... so we're burning money on broken displays while looking for more.
