Nice idea but not working in practice

Used it on a 10 day trek in Ladakh where the water was very clear. The pump worked great and really fast for the first 10 liters or so, after that it went slower and slower, even with regular back flushing. I think I got about 50 liters out of it when no back flushing could restore it to a usable state. As said the water was already clear to begin with so this was quite disappointing. Fortunately we could still boil the water and there were several springs on the way that proved safe. Fortunately I got full refund. Next time one I'll get one of the ceramic filters, they are harder pump and slower, but at least the keep working and can be cleaned more easily.
