User Review: SteriPEN Adventurer Opti
Price Paid: $72 on sale
There have been a number of SteriPens over the years and this, the Adventurer Opti, was new in 2011. After looking over the mostly favorable reviews of the previous SteriPen Adventurer, I bought an Opti in spring 2011 and have been pleased with the results so far after a season of use.
It is similar to other pens, light, small, uses two batteries, etc. It is compact and very easy to use.
Just returned from a week long backpack in the Eagle Cap Wilderness in northeastern Oregon where my group of three used it daily as the sole water treatment system. When using in bright sunlight it can sometimes be hard to see whether the device is on.
Otherwise very straightforward, easy and quick. Can always use a coffee filter to filter out debris or particles.
