I have twelve of these. At bottling time, this is the only way to go. Easy to manage, pop them on and off the Fastwasher, also use them to store freshly rinsed bottles (I rinse bottle immediately after drinking it). Trays and racks clean up easy. They don't stack securely, and the trays are all sort of warped, but I don't like stacking them anyways, and the trays flatten out quick when there are a few bottles in the rack. So overall, I still think these are a five star item.
