I like(d) my pair*. They're light, bright-ish and the USB charging is pretty handy, as long as you make sure to pop the charging dongle on your keyring and not lose it.
The front one only lasts just short of two hours on max brightness, and even then it's not hugely bright. It's fine as long as you simply want it for visibilty rather than hoping to light up pitch black country roads at 15mph+. I had to buy a proper man's light for the Dunwich Dynamo, for example.
Road.cc benchmarked it against proper man lights, here:
