I use the filter and find it good.To aid filling as water scoop I re-use those fairly stiff plastic coffee, pills, other food product bags with sealable tops.
I use a child's juice foil 'carton (like a pouch). Cut open the top and it makes an ideal scoop by gently squeezing the sides, only problem is that it is only 200ml, but, if you need water, you'll have to take as long as it takes.
My kit consists of :
Sayer Mini water filter
Platypus Inline carbon filter (to remove 'taste')
2x 500ml Bladders
2x Non-Lubricated condoms
10x Water sterilising tablets
Assorted bits of pipe and connectors for different assembly and filtering methods
It all fits into an 'Airline Courtesy Kit' holder. (the kit with toothpaste, slippers, socks etc)
