I bought this bike light set mainly because the front and back lights are BOTH rechargeable (unlike some other sets), and although some reviews claim that the front light is not 1200 lumens, I find it more than bright enough, even in the daylight.
PROS:
1- Very bright 2- Recharges in a short time if you recharge it after each use 3- Lasts a long time on a single charge 4- Six lighting modes for the front light, and four for the back 5- Both lights can be easily attached and detached from the bike
CONS:
1- The rubber straps that hold both lights to the bike could be a problem. If you loose the front one or they break, you will have to jury rig another way to attach them--just something to keep in mind.
Overall I think that these lights are a very good product, so much so that I have purchased a second set.
