Excellent device. Worked flawlessly on the first week's fishing trip in northern Sweden. Easy to use. Batteries/batteries were enough at least for that trip. As an improvement: the fastening of the battery/battery case cover could be better and protected with an O-ring.

Great product, made very well. However I would recommend including rechargeable lithium batteries, with an external charger. Which is more sustainable, than one time use lithium batteries. Varuste shipped the product quickly and it arrived very quick.

Several Classic models have been used successfully in the economy for a longer period of time, the latest of which, however, broke down as a result of the impact. Ended up with the Adventurer model due to its smaller size and weight. The light shield is clearly more sturdy than the Classic model and the construction and shape are such that I would think it would be more durable for travel use. Significantly smaller size and weight a big plus. Absolute minus a special battery standard. In practice, longer trips are required to carry spare batteries if there is uncertainty about their availability. I recommend the model if you want an effective purifier for the smallest and lightest clear water for the eye. However, if weight and size are not the number one consideration, I would choose the model to be downloaded from the Steripen collection.

Easy to use and drunk without getting sick tap water in Nepal, so I dare say that it works. Significantly saves plastic bottles / nature and money. Great for hiking. The Pre-filter itself is an addition recommended to remove larger particles from the irradiation path. When buying, pay attention to the type of battery, which is a little harder to find than usual (here one * drop)! Apparently in cold temperatures Opti works somewhat better, at room temperatures I would buy Classic.
