Pro Great for darker rides
The Cygolite Expilion 850 is one of the brightest light for the price. The highest setting emits 850 lumens of light which is great for roads with no lighting at all like in rural areas or off-road trails. Even on the lower setting it's still bright enough for non-illuminated bike paths.
Pro Has a handy mount that won't require you to re-aim the light each time
The mount on the Expilion 850 clips around the handlebar, and then you slide on the light itself on the stationary mount. That means, you only have to aim the light in the direction of your choice once, and it will maintain it's direction when you come back to it.
Pro Good battery life
On the highest setting (850 lumens) the battery will last for 1.5 hours, and on the flash setting for 22 hours. This is more than enough to get you through the week on one charge.
Con Mounting can be tricky
The rubber mounts are basically straps that hook around the handlebar and hold the headlight in place like a band would. This allows the light to slide forward or backward, especially on bumpy roads. Sometimes, the rubber mount can break, but you can get replacements from their website.
Con The mount may be too small for your handlebar
It's supposed to fit all handlebars, but there have been cases where the screw holds it together by just a few links. Be careful if you have an extra thick handlebar.
