These buckets are ok but they would get more stars for the following:
1. Put some hashes on these things to show amounts to make it easier to show proper ratios.
2. Strengthen up the bucket. When you lift the bucket rather full, it nearly creases. Also, when you use the bucket dolly, when you screw the holders in place the bucket just pushes in holding nothing.
3. A little deeper would be nice to have more room for grit guards and so forth.
