I purchased the dark blue model about 1.5 years back. Although it is slightly wider than some bottles, making it awkward to fit a cup holder of a typical golf cart, i love it! The internal straw means I don;t have to tip it to drink. The push to close valve is easy to operate & totally water-tight. The bottle keeps liquids cold in 38c temp's for at least 5 hrs (golf course play time duration). I have also purchased spare seal rings, tubes, etc. in case I loose or damage them during cleaning. I would, and have, recommended this model to many fellow golfers & those who walk / drive places.
I would recommend this to a friend!
