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.

Comments about Knog Blinder 4 Rear Bike Light:

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.

Could Not Use

Comments about Knog Blinder 4 Rear Bike Light:

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.

Service and delivery comments:

REI accepted the return no questions asked.

Almost perfect

Mount Needs Improvement

Best Uses

Rear safety light

Comments about Knog Blinder 4 Rear Bike Light:

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.

Comments about Knog Blinder 4 Rear Bike Light:

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.

Comments about Knog Blinder 4 Rear Bike 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 !

Heavy Metal Clip

Won't Turn On Anomaly

Best Uses

Rear safety light

Comments about Knog Blinder 4 Rear Bike Light:

The light would not always turn on, a lock-out anomaly. (To unlock it, momentarily plug the light into a USB charger.) I returned it to REI after being locked out on the road, twice. I did not get another one.

I also disliked the heavy, clumsy metal clip attachment.
