CFA LEVEL 2 25th Hour notes

Hi All,

Just wanted to know the reviews of 25th Hour CFA Level 2 notes if anyone has gone through it.
Is these notes good enough to cover the major testing topics for the exam. How much reliable can they be? And also has anyone tried the question bank of the same?

From which provider? I know Wiley has an 11th Hour Guide

Provider is Havels Learning System®. I cannot find much reviews about them!
