"I like that the filter is hermetically sealed in plastic wrap. However, I wish that it came with a foam or soft wrapper to protect the plastic wrap from easily being punctured in my pack. I found an extra wide koozie (neoprene) that fits it comfortably. A “Use By:” date or manufactured date would also be nice. I’m not sure when I’ll need it so a date of some sort on the filter would be great."
"As a van lifer, a hiker, an adventurer, a traveller, an explorer and prepper. The Grahyl goes everywhere with me ive used it to drink from streams rivers and waterfalls all over the world from the peaks of the UK to the rain forests of Borneo. A good quality proven and trusted piece of kit. Worth every penny dont be fooled by cheaper knock offs or by other sub standard filters the Grahyl is 100% essential kit."
"I understand writing a review about a cartridge is what this is about and I will say that I’m very impressed with the entire system, especially with the ease of changing cartridges while on the go. I use my Grayl everyday compared to my Spouse so our usage is drastically different but the ease of use, quality of water and maintenance go unchanged. I like your products so much I purchased two additional systems for my friends living in Colombia after the 7.4 earthquake a couple months ago."
"So far, I’m really liking my GRAYL. I took it on a camping trip, and the water tasted good. It costs a little more than the Epic Water Filters bottles I’ve used for the past four or five years, but I like the construction and the press design. My Epic bottles worked well, including at military facilities where I prefer to filter my drinking water. My biggest complaint was the effort needed to draw water through the filter attached to the straw. With the GRAYL, once you’ve pressed the water, you can drink freely from the open spout. That’s probably my favorite feature—you can take a good drink without having to work for it. The pressing process takes a little getting used to, but I really like the concept. I’ll be carrying it around a military facility for the next three days, too. Still early in my ownership, but my first impressions are very positive."
"This bottle is great for peace of mind while traveling, bot just hiking. If you drink lots of water and hate wasting or lugging around water bottles while traveling this should be your go to solution. Im buying a second one already as my girlfriend stole my first one. My only comment would be for people with a weak grip strength removing the external sleeve to fill with water could be a bit difficult but for most people the grippy material on it is sufficient."
"Greeetings. Received the replacement cartridge just fine. However there is a clear plastic insert into the opening displayed in this image that was not included in the replacement. Was that a miss or should that plactic piece not have been used or included in the original order? I'm concerned regarding the effectiveness of the filter with or without it. I leave for a trip Friday when I was hoping to use the GeoPress. Now I'm frightened that I may not be protected like I'd hoped. If anyone can call or email me to reassure me of how to use the replacement cartridge, that would be helpful. 678-362-6477 or 569rbw@gmail.com"
"Great product for filtering water if you’re traveling or on the go. Love the peace of mind this brings. Great travel size and quality filters that do an excellent job."
"Cool product but just does not perform like advertised. Im just so disjointed in how hard it is too pull the 2 bottles apart to put water in too press. And ontop of that I used it 3 times in a creek that was totally clean and just after 3 presses its almost impossible to push down and take almost 45 seconds to fill. Ontop of that I doubt they will respond of do anything to keep me as a customer. Filters are 36 bucks plus shipping. Big thumbs down from me. Id like to ad I live in alaska and spend alot of money on hunting equipment. When I saw this product I had to have it and im just really upset with how its performed."
"The cartridge is very easy to change, and is a great thing to store multiple backups. You can never have too many replacements stored away."
"I love my Grayl water bottle and filter. As an avid hiking, it’s indispensable. It’s easy to use and lasts a long time. I even tried it in nasty tap water with great tasting water as a result. It is a great product!"
