Worked great for a few weeks, stopped working after first battery life cycle, I'm currently waiting on a response from customer service, I would give higher ratings if they replace, I'm hoping I just got a lemon because I loved it when it was working correctly
CatEye Volt 700 HL-EL470RC reviews
After about 3 weeks of near daily use, I decided that this may be the best headlight I've owned. This was a substantial upgrade from the CatEye Nano, which itself is a good commuting light. The Volt 700 is very useful on the unlit multi-use path part of my ride home in the evening and on the better lit neighborhood roads as well. I think the dynamic setting, which flashes briefly to max brightness from a base light level, is good for lit city streets while bringing attention to the rider. The mount is the same as the Nano, and is strong, compact and simple as others have noted here. I purchased the charging cradle to make charging up at the office easier (it is compatible with Volt 700, even if the description says otherwise).
It's also worth noting that the light is bright enough for visibility during the daytime, especially in flashing modes.
I've yet to drain the battery on my roughly 30 minute each way commute. I tend to place in the charging cradle every 3 days or so to charge. Also, I debated about ordering the Volt 1200, but glad to have chosen the lighter 700, which is plenty bright for my needs.
