Used for a recent trip. Love that it is so lightweight, compact and easy to use. Fitted a cheap unknown brand of foldable plastic bottle on the inlet end (could screw in without leaks), to dispense into our water bottles 1-2x per day. Flow rate is acceptable

Love the Lifestraw series of filters. I have almost all of them. The original one that I bought 4 years ago, the one in the bottle, the metal one and now this. the problem I faced with this one is that there were no instructions on how to attach it to a regular 500ml to 1 litre bottle. I kept on trying to pull out that end that has the cap, while all I needed to do was to unscrew it clockwise and anti-clockwise to put it back on. I thought it needed some attachment that I might need to buy separately. What the packaging lacked was a simple arrow or words that said (unscrew cap to attach on bottle). Also, why Flavor stars in the rating system?

I absolutely loved using this filter on my ABC trek in Nepal. It kept my mates and I healthy and safe drinking from a wide variety of.. questionable water sources. I will absolutely buy more of these In future. The only problem is we only had one so it took a while to filter water for 4 people
FUNCIONA MUY BIEN, PARACTICO PORTATIL, VALE LA PENA, TE SACA DE UN APURO

I had a really disappointing experience with this product. The water flow was extremely slow, making it hard to drink properly. It felt flimsy and not as durable as expected for outdoor use. After just a couple of uses, it started clogging up. Definitely not something I’d rely on in an emergency. Totally let down by the quality.

The product requires back flushing and care while using and storing, purchased for the suspicious water filters which are rarely cleaned.
and i don’t think the filter can be replaced for this one. Go for a bottled integrated one for traveling.

The product is excellent for great Water Filteration on the go. And the seller Great Rocksport is also very Good.
I want to bring to notice to anyone buying this, that the product comes in a cardboard stand which does not fully cover the product, but a good Bubble Wrap is provided. Also to note that there is a slight dot sized dent at the bottom of the plastic body of the product, and this comes from manufacturing in all the units, so don’t be bothered by it.
I had a doubt about this, and so I contacted the seller and also ordered a replacement. I received the replaced product with good cooperation from the Seller Great RockSport.
And also there’s a Charity work to provide clean water to the unpriviledged with every purchase.
Thank you everyone.

I had to go far to fetch drinking water from water atm. Moreover I had to be me on the mercy of friends. This filter have made my life easy. I have also found a new travel buddy for treks and solo bike rides.
Point to be noted if you unwind the cap it fits a normal plastic drinking water.
Quality of water (tastes and looks) better than RO used in public water ATM and dispensers.

I travel a lot, and sometimes to the northern Hilly regions of UK and HP. This is a great accessory to carry. When I dont have access to mineral water (e.g. home stays) I use this to run the water through once.
One drawback is that the product doesnt fit the head of KINLEY bottles.

Super efficace ! La matière composite est cependant fragile. En vissant la seringue de rinçage … le pas de vis femelle a cédé… dommage.
