"Really handy, lightweight filter. Convenient when it works. However, when we took it for a multi-day backpacking trip, it completely stopped pumping. Like other reviews mentioned, we were lucky to have a backup system to purify water. It has been carefully stored and lightly used but is not completely not working. Unreliable."
"Sadly I’ve only ever used this once and it worked great. I really wanted to use it again I bought it few years ago and I keep testing it out at home and the water sprays everywhere and the cap keeps coming off. I tried soaking the red piece in water as it may be dried out and screwing it on as tight as I can and the water keeps spraying everywhere. The replacement part is also so expensive. I wish the product worked as reflected in the price."
"Small and light makes this easy to always have on hand. When I’m travelling alone or if I don’t think I’ll have much need for a filter then this unit is the perfect one to bring along. Simple to use and faster than you’d expect"
"My original Trailshot filter wasn't pumping correctly, but with some Fantastic Customer Service assistance from MSR, I was able to get the part I needed and my pump works incredibly well. I keep it in my daypack, but I am I am almost tempted to leave my almost 30-year old trusty MSR MiniWorks home on my next trip!!!! Thank you MSR!!!"
"I purchased this filter when it first came out circa 2018 and had used it for years. I recommended it for my brother-in-law and he bought one, too. I saw that some improvements were made with his model and the flow was significantly better, so I purchased a new filter cartridge. This improved things for my filter and I used it for a few more years. After getting my sister into backpacking and letting her borrow my first Trail Shot, I decided to pick up another in 2024 for myself. This one has given me trouble after just a few trips, and on the last trip it was not usable. The flow was so restricted that all I could get through the filter after applying much force was a slight trickle—not enough to make it usable. Thankfully my buddy had his Sawyer along and we got by with that filter the remainder of the hike. I don’t know what went wrong with the Trail Shot. I’m meticulous about maintaining and storing my gear. After every use I followed the cleaning and storing instructions. I would love to be able to recommend this filter because it is great where there is limited water along the trail and in situations where it is impossible to scoop water or place a bottle under a trickling water source."
"Exceptional water filter! Just completed a one day Teton Crest Trail run and used this filter along the way. Easy to use. Lightweight. Accessible. If you know how to milk a cow you know the rhythm to use! This was a confidence booster too knowing how easy it was to use. This really helped with frequent hydration along the trail as we ran. Looking forward to using this filter again. A must for any future back country adventure run or hike! Coach Kirk"
"The best, most compact water filter I've ever used. So great for spring mountaineering missions with lots of snowmelt!"
"I have used this product for three years. I rotate between two of them during the year. Primarily used during backcountry hiking / fishing trips. Pros: -Size and packability - Very easy to use Cons: - Mouthpiece cap pops off when pumping - replacement cartridge is expensive -"
"I really wanted to like to like this filter given that it's very light and relatively inexpensive. Unfortunately it was too good to be true. After three seasons of limited use the filter no longer works. I've only used it 3-5 times per season (nowhere near the 2,000L filter rating) with clear lake water and I've always followed the instructions. On a recent trip I was stuck with a useless filter. Luckily there was another filter in our group that we could use. I wouldn't recommend this water purifier."
"Super light weight and fast to filter water. Used it on a 5 day backpacking trip and had no issues"
