    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.

    Scalex MapWheel is rated 2.0 out of 5 by 1.
    Rated 2 out of 5 by from too inaccurate for backpacking routes I hate taking things back to REI, it hurts us members. Nevertheless, I took this back. It is supposed to be accurate to within .25% (that's one-quarter percent, not 25%). I got it close to that on a 12" straight line, but on a typical switch-backing hiking route, it's useless. The wheel is too big to roll along accurately on the map, and you end up way off. A route that I know to be 18 miles came up as 12, that's not helpful info for planning a hike. So this thing might be good for planning driving routes, where being off by a few miles doesn't matter (but with the internet mapping services, why bother?) I wish it would work for hiking. If somebody could just come up with one where the measuring is done by a rolling ball like in a ballpoint pen, then you'd have something. Until then, take a pass. In fact, I recommend that REI drop this item.
