I've used it with my team for a couple of years and I don't really dislike it as long as people don't take it very seriously. It is mainly a tool to reason about what needs to be done. It's interesting when someone gives a 2 and someone gives an 8. Why 2? Why 8? Discussing about a thing makes it clearer what may be complications and things to be aware of. Honestly I don't care about the number themselves and probably three levels are enough and may well be orange, apple, banana.
