Rated 4 out of 5 by from Fast and efficient I bought this filter four years ago and have used it on numerous occasions. It's fast and efficient at filtering and pumping water. While it is easy to use it it takes a little bit of practice to get used to cleaning the filter in the field. I would recommend that you do this at home several times so that you have the steps down and also you have the process correct otherwise it can be quite diffi it takes a little bit of practice to get used to cleaning the filter in the field.

Rated 1 out of 5 by from It was great while it lasted I take a week to two week back country trip every summer. I purchased a HyperFlow and it lasted many years with heavy use for those one to two weeks a year. The HyperFlow would make crystal clear water out of some very questionable water. Then one year on the ascent of Roan Mountain on the appellation trail, the unit broke and would not function at all we had to hike into town to buy bottles of water. I purchased another HyperFlow the next summer and took it on a multi-day kayaking trip. It broke the first day out. I really want to rate this product higher. When it works, it works great! But after having two units break in the field, I can no longer trust the HyperFlow to be their when I need it.

Rated 1 out of 5 by from Not worth it! I bought this after reading many reviews and knowing that MSR makes great products (normally). I used it on two backpacking trips and returned it to buy a Katadyn instead. The lightweight filter pad kept flipping over in a stream (not a raging river, but a babbling brook) so I basically had to hold it in the water while someone else pumped. Then the pump started sticking after only a couple liters. The pump is also a little awkward to hold. At the time it didn't have the big mouth adapter, so that would be a welcome change, but having the water container right there is a pain. For the money, you can do MUCH better.

Rated 3 out of 5 by from Hard to pump hyperflow We have used the hyper flow pretty extensively (every weekend all summer), and made sure we backwash it on regular basis. It got to the point where it got so hard, that we didn't want to pump anymore. Checking the filter and washing it on the tap at home, and watching several youtube movies to see how else to make it better didnt help. One of our guests ended up breaking it while pumping and we ended up getting the auto-flow mini filter, which is definitely less work to get water.
