I have used a platypus system for years after using a pump before.
Love the platypus. Have never had a problem with plugging or speed.
I use it in the bush in Canada every year for some time now and it works great.
I need to get a spare bag, but otherwise no complaints.
It probably wouldn't be ideal if there was just 1 person. But, if you are procuring water for a couple or more people, it's the [bleep].
