    The REI Member Dividend

    The REI dividend is a unique benefit of membership in the REI co-op. It's comprised of your member refund—typically 10% back on eligible purchases—and/or your REI Visa® card rebates.

    Each March, active REI members and REI Visa cardholders who earned a rebate receive a refund in the form of an annual dividend notice.

    Only active members receive annual dividend notices. To maintain your active status as an REI member, you need to make net merchandise or shipping purchases of at least $10 per year, unless you joined that year. Member numbers are issued in one name and only that person receives the member refund. Your number can be used by others in your family, but it cannot be transferred to someone else.

    • SteriPEN turns itself off once ultraviolet treatment is complete; can be used up to 3,000 times!
    • Watertight seals keep water away from the electronics; rubberized inset grips for secure handling in wet conditions
    • Low-power indicator lets you know when batteries need replacing; twist-off cap for easy battery access

    SteriPEN Traveler Water Purifieris rated3.5out of5by4.
    Rated5out of5byfromquick and easyAfter much research, I chose the Traveler instead of a pump purifier or even one of the other SteriPen models. I used this product twice on two 30 mile treks through the high sierra. This product is super fast (90 seconds for 30 oz.) Also, it is so simple, you press a button, swirl it in the water, and wait for the light to turn off. That's it! It has the EXACT same efficiency as all of the other, more expensive SteriPen models, it just doesn't have smiley faces and an LED screen, and explicit instructions on how to know when you are finished with water treatment. It is only slightly larger and heavier than the other models, but still so compact. This model was only $50 and worked just as well as I'm assuming the others do, it just lacks the bells and whistles. If you read the manual and operate it properly, you should have no problems. This happened to be my favorite and most useful item I purchased out of all my backpacking equipment. I LOVE IT!

    Rated1out of5byfromUnreliable....Sure glad I had backupWe planned to use this to purify our water on backpacking trips. We had a little success on our first trip, but lots of error messages. On my most recent trip I got it to work only once, spent a bunch of my evening frustrated, re-reviewing the instructions, trying to get enough water, and ended up using purification tablets instead(SO GLAD I had them along. Perhaps our unit is defective; regardless I am returning it.

    Rated3out of5byfromSeems to work but has some quirksIt was great that I had this along on a recent 10-day backpacking trip in the Sierras when our primary water filter system broke on the second day. Worked great except for one day when it kept giving an error signal that the water-sensing pins were wet. Finally started working again after leaving it open in the sun for an hour - I suspect there was some internal condensation. I also experienced some issues when previously testing it at home. Sometimes it gave a 'lamp failure' indication instead of turning on, but trying again it would work normally. So I'd only recommend this item if you also have some other means of water purification along. But on the plus side it was much easier than pumping through a filter.
