I used this tool recently to debug some issues where one of our batch tasks was using more memory than it should and sometimes OOMing in an environment where it shouldn't come close to hitting a memory ceiling. Found the issue almost immediately with the high watermark analysis which provides visibility into the part of the codebase/call stack that allocated every bit of allocated memory that was still live at the high watermark time. Made diagnosing the issue (an unexpectedly large amount of memory required when using a method from a third party library -- xarray.merge) and remedying the issue incredibly easy. I was very impressed by the quality and utility of this tool and am now a huge fan!
