Bag leaked, flow rate seems slow
- I've used it several times
I purchased this right away as I own the Guardian pump version and not having to pump water would be awesome. I feel like the flow rate was very slow, likely due to water having to travel through a much tighter membrane in the purifier cartridge. The main problem was the bag leaked water out of the outlet and I was attempting to test it indoors. They show people using it in all sorts of places, but if you have a leaky bag that will be tough. I repeatedly contacted MSR support and never received a call back. It would have been nice if they were responsive.
