Your review: We are using these bins and a transport down a roller conveyor to their next work stations. They are just the right size for our parts.
Pros: They are the right size for our parts, and they move down the roller conveyor smoothly. It works well for our purposes.
Cons: The parts we are moving are steel, and over time the bins start to crack and break from the stress. We have also had feedback from our customer that they have found small pieces of the bins in their parts. When they start to break we have to replace them. Ideally we would need some kind of metal bin the same size and shape as this one.
