Other Thoughts

The Bike Snob NYC was hawking these pretty consistently for years so I thought I'd give it a shot. Bought both front and rear and commuted with them. They're solid and effective, I've had no issues with them at all. They mount quickly and the usb charging on them is super cool.

Ownership: several months

Other Thoughts

The silicone mounting system looks and feels weak or fragile, but it's not. "Looks" might be "deceiving", and they're often our sole decision-making criterion, so why not beef-up the bands?

I'd equally appreciate a longer battery-life for the Fast Flash light mode -- although the manufacturer's website claims 3 hours for steady use, and 50 hours in Eco-flash mode, my light runs out of lumens after 3.5 hours of Fast Flash operation (yes, I recharge fully after every ride).

Other Thoughts

I love the size and portability of this light. It is fighting for space on my Salsa bars with a NiteRider Lumina 700, Light & Motion Taz 1000 and a BarFly out front for the Garmin.

It fits nicely with all the other pieces and allows me to be seen on my morning commute (5:30am) and on the way home (3:30pm). It provides just enough of a visual distraction to catch a driver's eye. It's saved me several times in the couple months I've owned it. Well worth the price and peace of mind it provides.
