    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.

    Planet Bike Protege 9.0 Wireless Bike Computeris rated3.625out of5by8.
    Rated3out of5byfromGood but...I like the display and what is on it. The issue is reliability. I've returned a couple of these because the unit stops working. Even after changing the batteries it won't work. When I can find a better computer that has similar info and is affordable, I will replace this one.

    Rated2out of5byfromMaximum speed erroneous.The computer mounted easily, has a nice tidy look without wires and shows everything I want to see while riding. It lacks accuracy, especially the maximum speed feature. It read 93 mph, 53 mph, speeds which I have never attained. My typical maximum speed is around 30 mph. The odometer seemed erratic, starting out it read high, i.e. 5.06 at the 5.0 mile mark, yet read low at the end of the ride, i.e. 25.33 at 25.44 miles. I know my route check points. I suspect the wireless feature may be the culprit. I exchanged it for the wired version at REI and so far it is working well.

    Rated5out of5byfromInstallation was simple, works great!I installed this on a newly purchased mountain bike, went to Colorado, ran it on tough terrain and it worked great.

    Rated5out of5byfromGood value for the costUse this in conjunction with my Garmin. The Protégé 9.0 and Garmin checkout very much the same. Bought for the temperature read-out

    Rated4out of5byfromsolid bike computerI've put 300 miles on my bike with it and never had an issues.

    Rated2out of5byfromHard to love.I recently switched to a 29er and this computer was INCREDIBLY difficult to program. It requires taking multiple measurements, calculating average wheel base coverage, and multiple manual inputs on a basic click-through interface. After all that it is only roughly accurate for speed and distance. I checked it against a GPS unit several times and it was off by about 3/4 of a mile after about 14 miles. The display is nice and large. Makes reading while riding tough terrain easy. I intend to return it and find one preprogrammed for my size bike. As usual the customer service at REI was fantastic.

    Rated4out of5byfromVery nice productI really like this computer. It gives speed, distance, average speed, top speed, time, and temperature. It mounts on the handlebar, and is easy to see there. It's really easy to switch between modes. I use it both when I'm commuting and when I'm training. Two drawbacks: You have to mount the sensor on your front tire, not the back. The top speed is not always accurate. It has given me a reading of 71 mph for a ride that was only on flat city streets. I don't go anywhere near that speed even coming down a steep mountain.

    Rated4out of5byfromDon't judge this product by price.We use them on our mountain bikes as well as our road bikes. We are very satisfied with the product and the price. I think the instructions show the wrong direction to mount the fork sensor. Could cause damage if the fork sensor was hit by spoke magnet. Unit works well with the fork sensor mounted on the front side of the fork instead of the back side.
