It's sturdily built and easy to use, and its quick recharge time and long burn-times in the flashing modes mean it lends itself well to year-round commuting...On the whole I like the Hecto Drive 500XL. If it isn't on the bike it's a good one to have in your rucksack. It's so small you can just bung it in in case of an emergency, working best as a be-seen-by light but capable of letting you see where you're going if you need it."
