    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.

    Knog Blinder 4 Rear Bike Light is rated 3.3 out of 5 by 10.
    Rated 3 out of 5 by from It is a good light except for the buckle I have used this rear light for the past 3 months and I must say I am fairly impressed at the design. It is aesthetically pleasing and functional. The light is bright enough to be seen even as the sun comes up and at dusk. It has many interesting light patterns. My only complaint is the buckle, it has a tendency to scratch the bike since I have to remove it after every ride, also the buckle has a tendency to come off.

    Rated 4 out of 5 by from Almost perfect This light is very bright, easy to use, and rechargeable. The only flaw I have found is that the mount is not very versatile. It consists of a rubber band with a metal latch that locks in place. Whatever part of the bike you mount it to needs to be a certain diameter in order for the rubber band to stay tight. It mounts perfectly on the seat post as a rear safety light, but I have been unable to find another place on my bike where it will mount functionally. Unfortunately for me, as a daily bike commuter, my rear trunk bag blocks the light when it is mounted on the seat post. This light is great but I wouldn't recommend it if you use a rear trunk bag.

    Rated 1 out of 5 by from Returned to REI Immediately I could not use the product. I tried charging the product overnight. I tried turning on the light in the morning, but it did not work. I continued to charge it during the day while I was at work. When I came home, it still would not power on. I returned it to REI in San Antonio. The cashier looked at it and noticed the battery contacts were corroded.

    Rated 1 out of 5 by from Critical let down While commuting to work, I am often caught after dark, and need my taillight. I like to leave it fully charged and ready to go for just these occasions. You can imagine the dissapointment and worry when you reach for your light, and it has discharged itself completely (WITHOUT USE) and you are left stranded!

    Rated 4 out of 5 by from Great for rear helmet light I'm very pleased with this Knog light. Great variable flashing modes. Decent battery life. I love that it's rechargeable. It's perfect for mounting on back of helmet for additional safety at night. Silicone strap is very stretchy. I guess my only complaint about it could be the buckle itself, but it hasn't given me any trouble yet. Knog uses responsible packaging too !

    Rated 5 out of 5 by from Awesome, couldn't be happier Love it, works awesome. The only thing I would change is the mounting. I wish it had a permanent mount and just the light could be removed. I don't like leaving the light on the bike all day while I am at work and the strength of the silicon strap that mounts it to the seat post worries me, I just hope I am not wearing it out taking it on and off everyday. Otherwise I love it and would purchase again regardless, that's how well it works.
