I have very little reference for quality and price of lighting, but some reviews online brought me to the dayblazer.
The rear light has been great in traffic on it's blinkiest setting and lasts for a good while on that setting. It's bright enough and blinky enough to keep the cars aware, but I don't think it would do the best job if you were out of a city in the dark.
The front light is bright but I don't love the blinky settings. Battery drains a bit too quick for my liking on the static light settings, but the blinky settings are pretty good and still provide enough light. If you're out of a city at night this might not be enough, but on dark streets or in Golden Gate Park in San Francisco this was good enough to help me find potential hazards on the road with enough time to move out of the way (15ish mph). The battery can go for most of the day if you're on a blinky setting.
Again, I have no reference here but it feels like the battery isn't all that good, and you have to completely unmount the rear light to charge it. The rear light may be enough for my commute, but I don't know if I'd trust it outside of the city.
