Quality bottle perfect to drink a gallon of water from

Definitely the best water bottle I have had. Worth the money!! 

It does the job but caution, it won't take a knock so be careful!

I drink 4 litres of water a day every day, this gallon jug is just perfect as it holds the right amount of what I need instead of me going back and forth filling up bottles constant throughout the day.. it makes it that bit more simpler!

Thought the bottle was a good purchase, it fell from a side table onto the floor and immediately shattered the bottom so 3 gallons of water leaked everywhere. Why are these bottles so brittle?
