User Review: SteriPEN Traveler
Price Paid: $65
After three years using the Katadyn Exstream bottle and dealing with the iodine after taste the Steripen was a welcome addition to portable water purification.
There is little difference in weight between the two purifiers if you include your water bottle with the Traveler but cleaning a batch of cooking water is much easier than the squeeze bottle method.
PROS - Very light weight, super quick purifier for relatively clear, non turbulent water sources.
CONS - Not a good unit for pesticide loaded, muddy water, best stick to the Katadyn for these sources.
Conclusion - I carry both the Katadyn Exstream and the Steripen Traveler. I use the Katadyn's bottle with the Traveler and keep the Exstream's filter element in my pack for backup.
