The Lifestraw Go is the first filter bottle we’ve used that has adequate flow rate. While it’s not quite like gulping down a liter of water, it gets the job done at lunch. Highly recommended for freshwater day-trips in calm water or for making a nice combination with gravity filtering system. Unfortunately the LifeStraw Go has a fatal flaw: Knock the bottle around long enough and the filter (held in place by friction) can come loose, allowing contaminated water to compromise the filter attachment. Treat it gently and all works fine.
