    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.

    Black Diamond Cosmo Headlampis rated4.3137out of5by51.
    Rated5out of5byfromWorks GreatI bought this for a weeklong hike in the UP of Michigan. Worked great with no problems. I really liked the different settings. Only complaint is that the band can be hard to get comfortable

    Rated5out of5byfromPerfect for campingThe perfect amount of lighting for camping and definitively waterproof. Lightweight. Haven't used it for other purposes but I definitely will!

    Rated3out of5byfromNot quite bright enoughGreat little headlight, small, good battery life, durable, fits on my head well and I like the ease of adjusting the head strap. Ultimately though it JUST ISN'T BRIGHT ENOUGH FOR ME. Still I think it's a good product if you don't need super bright lighting, such as around the house, on trips with enough moon/starlight or other outlying city light.

    Rated3out of5byfromCool but with one big frustrationThis headlamp was mostly used in everyday life. It was mainly kept in my purse and backpack to use when needed. I use it quite frequently, like running to the car or walking the dog at night. Nice and bright. I loved how it would dim down too. However, the power button was always getting pressed by whatever it was next to in my purse or bag. So the battery was constantly draining. I've had a number of headlamps in the past and never had this issue. I always had to double check that it hadn't been turned in again. Besides that a great light. But I wouldn't buy another one.

    Rated4out of5byfromSolid HeadlampI recently used this lamp on my 21 day backpacking trip of the John Muir Trail. Lamp is bright and I hiked at night with it several times. I also used the lower lamp setting to read in the tent in the evenings. Battery is long lasting. The only problem I had was the confusing switch from the red light setting back to the regular setting.

    Rated5out of5byfromBlack Diamond Cosmo HeadlampBought this to use for overnight backpacking trips. Haven't used it for that so far but have used it around the house just testing it out. Love it so far!

    Rated5out of5byfromNice light settingsBought this to replace my 10yo petzl tikka. Chose it for the multiple lighting settings - I recommend going to a store and testing out the headlamps on display to determine which one has the brightness/settings you like. For me I like the multiple levels of brightness for white light, multiple strobe settings for both red and white light. I use this light for backpacking, car camping, & cycling - a nice well rounded light for the different tasks I use it.

    Rated4out of5byfromGreat valueNeeded a new head lamp for a fall canyon trip to Utah. Knew I would find the one I bought last year (doh) when I came back from the trip, so was looking for price/performance. This head lamp got all kinds of comments for its brightness on the trip and it didn't break the bank.
