Looking at customer feedback, we can see that users really appreciate the Peak Squeeze's easy-to-use nature.

The Katadyn BeFree 1.0L makes quite an impression with its ultralight design, weighing virtually nothing at only 2.3 ounces. It’s the sort of thing you can pack and forget about until you need it, making it perfect for those long, adventurous hikes where every ounce matters.

Users appreciate its fast flow rate adding that unlike some other filters, you don't have to squeeze like a maniac to get a drink. The BeFree takes just about 40 seconds to fill up a liter, which is quite impressive. You'd think for something so lightweight you would have to compromise on speed, but the Katadyn BeFree proves otherwise.

The thing that so many backpackers love about the BeFree is how super easy it is to use. Its wide mouth opening makes it surprisingly simple to fill up in rivers or streams – it’s not one of those where you have to faff around for ages just to get the water in. Instead, you flip the top, collect your water and you're good to go.

There have been a few concerns raised about its durability. Few users have complained that the filter started to slow down after sustained use in particularly grubby water. However, the majority of the reviewers have found that the filter performs optimally, even after considerable use. Like all water filters, regular cleaning is required to maintain its efficiency over longer periods of time.

Some people have remarked that, while the filter can be cleaned, it's a bit fiddly to do so and certainly not as straightforward as it is with some of its competitors. However, others have suggested that it’s a small price to pay for the convenience and weight saving that the Katadyn BeFree offers.

The bottle feels flexible and is made in such a way that it can be rolled up and stashed in a pocket when not in use. There are those, though, who pointed out its lack of rigidity as a downside, stating the soft flask could potentially puncture. Its long-term durability in harsh conditions does appear to be a concern among some users.

Despite the minor concerns about its durability and cleaning, the Katadyn BeFree 1.0L generally receives high praise for its feather-light weight, fast flow rate and ease of use.
