Super durable and excellent quality, would reccomend to all!Was confused about not being able to find the year 2017 printed on it anywhere, but perfect, this is exactly what I needed. This is the most recent editionMy daughter took a lifeguard class 4/3/21. They wanted her to print out this manual. It was more convenient to buy it!Well yeah it’s a book what else do you want me to write, it came in good condition.This instruction manual was very informative and up to date with all its info. Easy to comprehend with pics to help assist you in the learning process.I would recommend this to anyone looking to become a lifeguard or just intersted in learning water safety .After using this manual, throughout the summer, for the life guarding program my child completed I've found that it was worth buying this gently used manual....no need for a brand new one because of the environment it's used in.It was probably a fine manual in it's time, however since the new manual came out this year 2017, it is now basically useless.I only gave it 4 stars because it had a large water stain on it. Otherwise, was just right .
