5.0 out of 5 stars Great for traveling and emergency use

I was traveling for 3 months around the US and concerned about the water quality in unfamiliar areas. Purchased this filter for travel and will keep at the ready at home for emergency use.

1.0 out of 5 stars I bought it and the product arrived damaged. It is in the refund process.

I bought this purifier and the first time I used it it didn't work. According to the user manual, the alarm shows that the device is damaged. For me it had been. For me this has been a big problem because I don't live in the USA and I bought this item for an upcoming trip to Nepal. Receiving a damaged item is simply unacceptable. Furthermore, there was no way to receive a new product before my trip, without returning the damaged one.

3.0 out of 5 stars Worked great but not worth it
Reviewed in the United States on September 17, 2023

It worked great for 5 months then the charge started getting worse and now it doesn’t even work anymore. No UV light. Red light blinking and green light blinking. Nothing. For 100 dollars this should be working for years not 5 months! Very displeased.

1.0 out of 5 stars not a simple green or red with success or failure
Reviewed in the United States on October 17, 2023
Verified Purchase
The product runs out of battery very quickly, its confusing if the product sterilized the water as there are so many variations of green and red combos. Most steripens just have green or red which I find easier. I understand wanting to let the consumer know that battery levels are running low but in the backcountry seeing red is just stressful.

2.0 out of 5 stars Unit won't hold a charge
Reviewed in the United States on September 30, 2021
Verified Purchase
I went through 2 of these. Neither unit would cycle more than 6-8 times before needing recharging. No where near the 20 cycles advertised. In both cases I got less cycles after a second and third overnight charging. Not something I'm going to rely on in the back country. I went with the (heavier) Traveler model w the CR123 batteries as a replacement.

1.0 out of 5 stars Tried 3 different units, battery wouldn't hold a charge on any of them
Reviewed in the United States on July 28, 2021
I had the older version of this Steripen product, from before they were absorbed into Katadyn. I used it on countless backpacking trips for eight years. When the lamp finally failed, Katadyn told me they didn't support the older product any longer (but didn't offer me any alternatives).

So I bought this, thinking it was the same product but newer. It's not. Katadyn have cheaped out completely. You can tell from the feel of the plastic case and the use of the Chinese Romaji font in the text printed on it. No one at Katadyn cares.

Basically, the rechargable battery on this thing won't hold a charge. After a full overnight charge (green light), I've taken this thing out in the field and gotten a low battery light on the first liter. After that I got about 8 liters purified before the battery goes out completely. For a product I am depending on for my life and safety in the backcountry, this is unacceptable.

At first I thought it was the unit I had, so I returned it for a new one. Same problem. My girlfriend got one of these around the same and hers has the same problem.

If you value being able to drink water safely while away from civilization, this isn't the product to do it with. Too bad. The older version of this was a classic product and they ruined it.

This works great. I have also dropped it while sterilizing and it was completely submerged with no issue. I noticed the TOC water test drops by up to .5. Easy to use.

5.0 out of 5 stars Great way to avoid plastic water bottles while travelling

Haven't used it for backcountry, but have used it for travel. It's a great way to treat local tap water to reduce buying plastic water bottles.

5.0 out of 5 stars crain un peu l'humidité
Reviewed in France on June 21, 2022
Verified Purchase
certains se plaignent que très rapidement l'appareil clignote comme si il ne restait que 100 purifications avant que le purificateur soit HS, après avoir été 6 mois a Madagascar, j'ai trouvé le problème, c 'est a cause qu'il faut le laisser sécher avant de remettre la protection plastique, sinon l'humidité qui reste sur le tube doit arriver peut-être a pénétrer dans celui ci et le détraque, après un bon séchage, il ne me détectait plus cette fin de vie proche.
le problème est que moi, je ne m'en servais que a la maison, mais pour les personnes qui sont en randonnée, il est évident qu'ils ne peuvent pas attendre que l'appareil soit complétement sec avant de reposer le cache tube. je n'ai jamais été malade même avec une eau pas toujours très claire donc très efficace, dommage que l'on ne peu pas stériliser 2 litres d 'un coup, car ça fais du boulot a 4 litres par jour x deux personnes.
