Collapsible Sinks?

[Ziradog]

Anyone use them?  Likes?  Dislikes?  I see some not much bigger than a dog bowl, others almost full size sinks with built in cutting boards and drains.  I keep breaking the cheapie plastic basins from Walmart, Dollar General etc. so I'm looking at alternatives.  Thanks for any input.

I have 2 sizes of collapsible buckets they take up little space on a small boat and seem to be sturdy. I use the small one to top off the water ballast tank on my scamp by dipping it in the lake and pulling it up over the side of the boat. I am very satisfied with them. I also have silicon nesting bowls with a top cover that I use to eat from. Very easy cleanup and again space savings. I haven't any experience with the sinks.
