David Thielwrote a review of Katadyn Base Camp Pro 10L Water Filter on June 5, 2016
Familiarity: I've used it several times
Bought this as a group filter for my scout troop. It works GREAT: easy to fill and hang, very fast flow rate, and simple operation for the boys. It is literally perfect for this use.
I use a Sawyer squeeze for myself—it's light and works well, but I must admit that it's a bit of a process to use sometimes. This Basecamp filter is so simple and easy to use, that I'd consider carrying it instead, even just for myself—and if they made make a slightly smaller one, I'd definitely make the switch.
The specs say it's 12.4 ounces, but that probably includes the hang strap, which you don't need to use. The included zipper pouch for your clean water tube is a nice touch though, and that will stay in my pack.
