Pros: Smart charger allows you to keep it plugged in without worrying about overloading or burning out the battery. Very Bright, I can see the spot on the ground during the day. Aftermarket lenses to widen the spot or use as a tail light.

Cons: Battery pack strap is rather weak, will not hold up to some serious riding but the bag has a loop in the back that you can use to secure it with velcro straps or cable ties. O-Rings used to secure it to your handlebars are a little weak too... a single cable tie looped over the cleats works a lot better.

Other Thoughts: Take a #2 phillips screw driver and near the rear of the light on the foam strip you will feel a soft spot, under the foam is the screw that attaches the cleat plate to the light, tighten it a 1/4 turn before you mount it and you'll never have to take it off to do so.

Pros: Bright. Battery lasts for hours. Fairly common light so you can get parts and modifications to it (different lens).

Cons: mount could be a little more secure but the o-rings work well if you don't have very thin handlebars.

Other Thoughts: i used a pad of double-sided tape to replace the foam to keep the light from traveling on my mountain bike

Pros: This bike light puts out 1200 lumens, its Extremely BRIGHT. My other mtb friends spent $100 on their lights and this one is 2 times brighter. the Long battery life is amazing. I used mine 3 times about 1hr each ride and it's charged up. I have mybattery pack mounted to the handlebar stem another light mounted to the right side. Highly recommend to all night riders.

Cons: Velcro strap is too long. I used a small bungee to hold the battery pack.
