Lightweight, but not sure how long it will last
on 17 August 2013
This does exactly what it says it does and the price is very good. However, the material of the bottle is like a very gauge polythene, so this may well have a limited lifetime - I'll update this review in a month or two once I have is more than a couple of weeks.
The only issue that I have found is that filling can mean that water goes all over the place the bottle cannot expand fast enough for the fixed flow rate from the water dispenser at work.
Having said all that, it is handy for the work backpack to make sure that I have some water with me on the (long) trip home.
