    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.

    Serfas USB Combo Light Pack is rated 3.1667 out of 5 by 12.
    Rated 4 out of 5 by from Decent Lights Not super bright, but a good lights for early morning/ night commutes. Haven't used them on the trail, but they probably wouldn't be bright enough or have a wide enough beam to properly see obstacles or wildlife in your path.

    Rated 1 out of 5 by from broke before I could use it The rubber broke the first time I tried to stretch it around my handle bar. I didn't even bother trying the back light since the seat post is a larger circumfrence than the handle bar. I bought the Blackburn Flea Bike Light combo for about $10 more and its smaller and didn't break.

    Rated 2 out of 5 by from Good idea, but needs some refinement I was hoping these lights would work well because they seemed easy & fast to get on and off the bike, and also because they are USB rechargeable. However, no matter where I positioned the tail light, my thigh would brush it as I pedaled. I have an athletic build, so it's not like the size of my thighs was the issue. Then, as I was taking the head light off to return the set to my friendly neighborhood REI store, the silicone strap snapped. I'd only put it on and taken it off a couple times. Disappointing! I really like the concept of the light set, but apparently they need some refinement.

    Rated 1 out of 5 by from Problematic battery The lights themselves are ok for being seen, but the headlight does not direct the light well enough to be a reliable light to illuminate a dark path. They charge in ~3 hours through a mini-usb cable (read, not micro-usb, I wish Serfas would switch to the more common micro port). The mounts are good and don't show any signs of breaking. They attach/detach very quickly. I have had 2 fronts and 2 rears of this model and none of them have lasted longer than 6 months. For all of them, the batteries have stopped taking a charge. I use them 3-4 nights a week for 30-50 minutes at a time. The charge required light is difficult to see on the rear unit. I would give more stars, but the fact that they've repeatedly refused a charge so quickly in their lifespan is very off-putting. I've since switched to the Serfas Thunderbolt lights and miss out on a lot of what I liked about these (easy to attach/remove, long battery life).

    Rated 4 out of 5 by from Very Happy with them I am an aggressive cruiser bike rider. Now that it gets dark early I need light. I live in a rural area and it gets very dark. This combo is great. The high beam choice does make a difference in total dark. The beam width covers almost 20 ft wide and reaches well ahead (75-100ft). My top speed can reach 25 mph and I see ahead fine. Faster riders may outride the light, but how many of you ride that fast in total dark? Some security house lights can overpower the headlights, mainly because they effect your eyesight. Not realy a fault of this product.

    Rated 3 out of 5 by from They are what they are.. A nice set of rechargeable lights..I use my solar panel to charge them. I ride daily in a not so bike friendly area, so nice bright lights are critical for safety and so far these are a good choice. I cannot comment on durability yet as I have had them only a short time. The battery quality and rubber band mounting system are in a "so far so good" status..A summer season here in southwest Florida will be a good test of durability..

    Rated 4 out of 5 by from Very Nice These are very bright and attach and remove easily - a big plus when you are chaining up your bike in the city. They are still new-ish to me, but so far, so good. They may earn that fifth star yet, time will tell!

    Rated 2 out of 5 by from Front is amazing, rear is useless I have been using the front version of this and the usb rechargable Knog rear light. The rear one died so I decided to get this combo because the front one I have is great. There rear one couldn't be more horribly designed. It mounts to the side of your seat post, so it sticks out to the left (or right depending how you mount it) and your thigh hits it with every pedal stroke.This may not be a problem for people on cruiser bike, but on a road bike it is terribly irritating. This is going back tomorrow. The front light is amazing, except it is annoying that there is a special cord that you have to not lose and have whenever you need to charge. Five stars for the front, no stars for the rear.
