Wiley 11th hour guide CFA Level 1

Hey everyone. I wanted to know if anyone used wiley 11th hour guide for level 1 and how good is it as I don’t know exactly what to expect when buying it, since there is no sample provided. Also I notice the 2015 version was 448pg while the 2016 version is 250pg. So what is different and does that mean that the newer version skips a lot of content? Thanks in advance.
