I find it a mix of really frustrating (mostly it not doing what I want it to do, making random changes alongside perfectly good changes of the type I want) and amazing when it works. With that said, I think it works best in an unconstrained environment, and when you start adding constraints (don't do it via this method, don't use this library or import any new dependencies) you find much less good results. This inevitably means it works better at the start of projects rather than coming on to something that's been around for a while and has it's own patterns.
