The light is very very bright.
T. Voros
The Portland Design Works Radbot 1000 is the best tail light I have ever used and I have been buying tail lights in their various incantations since 1985.
Ford Prefect
Thanks for reading, hopefully I've provided some insight into my personal reasons as to why this light is great.

I'd heard about the Radbot 1000 tail light and decided to order one and use it for my upcoming century ride.

It is a 1-watt LED with a large reflector below the light which gives additional visibility when approaching-from-behind car's headlights hit it. This one-two combo, a super bright flashing 1-watt LED and reflector gives it a significant edge compared to other bike lights. I also want to mention that the reflector acts as some sort of insurance that in the event your batteries die on you mid-ride in low or no daylight situations, you will still have some visibility as soon as approaching headlights hit the reflector. That is significant fail-safe mechanism in my opinion, at least in dusk to night situations.

Powered by 2-AAA batteries, you can expect about 30 hours of operation according to Portland Design Works but if you use non-rechargable alkaline batteries you will likely see the light lasting up to 50 hours or more in zZz Pop mode. That's what I get. Running the light in steady on mode will greatly reduce your battery life to about 12 hours (according to Portland Design Works. I never use that mode so couldn't advise you on that.)

It comes with a variety of mounting hardware that makes it convenient to mount, either on the back of a seat bag, or attach it to the seatpost or seatstay. Whatever works best for you.

Compared to the PlanetBike Blinky Superflash Planet Bike Blinky Superflash Tail Light which uses a 1/2 watt LED, the Radbot 1000 provides twice the light.

***December 2012 edit: This light is a different model than the one I originally reviewed. I have since bought two more of this model of the light and have not had any issues with it going out after a full year of use. The light modes on the current model are not the same as the model that I originally wrote the review for. I am a particular fan of the zzZZzzPop which was not programed into the original light. For the reason that I have not had any issues with this new version and the fact that it is now my favorite light for this price range I have increased my rating to 5 stars.

***Original review:
I've owned a number of bike lights since I started commuting exclusively by bike about 5 years ago. I normally ride with only one tail light. I bought this light 4 months ago and loved it. This is the brightest light that I've owned, definitely brighter than the superflash. The addition of the reflector is also a nice touch. One thing that I noticed though was that as the light is a 1W light it drains batteries noticeably faster than the .5 W lights that I've owned. That said I would still rate the light with 5 stars.

Why then 3 stars? As a previous reviewer noted, this light has issues with going off mid ride. On three occasions I turned on the light and 2 miles later when I got home the light was out. As I don't always ride in bike lanes and I tend to ride on busy roads and some that aren't really really well lit that scared the crap out of me (luckily there is the reflector). Then two days ago I turned on the light and it blinked for 2 seconds and went off. I turned it on again to the same result. The third time I tried to turn it on, it didn't come on. I changed the batteries, still no luck.

After 4 months it no longer turns on.

This is the best self-contained 2xAAA-powered taillight I have found. It "pales" in comparison to my "gold-standard" DiNotte lights (4xAA powered) yet it offers significant presence and observability for day-time precaution and impressive brilliance for forewarning motorists, by night. Amongst the light sequence choices is an intriguing, attention-getting, modulated-intensity-Zap-Zap choice.

The Radbot 1000 chews up batteries about twice as fast as the Viewpoint Flashpoint Ultra (another self-contained 2xAAA light) but here's the scoop for daytime safety and cycling enjoyment:

USE BOTH! (There's room on your seatpost to mount both).

Why two? (Radbot & Viewpoint).

Because the different sequences (and pair of slightly-offset lights) really alert approaching motorists to your presence. By intent, the different lights are NOT synchronized, hence the motorist's daze is interrupted and attention gained,long before a dangerous encounter might unfold.

Cycling is much more enjoyable and safer (by day, as well as by darkness) when the cyclist gains the motorist's attention far enough in advance that the motorist can figure out how to safely and courteously share the road with you, the slower road user. Riding is considerably more enjoyable, with reduced stress/hassle, when overtaking motorists on twisty, narrow, two-lane roads, pull out half a lane or even completely into the other lane for a wide passing margin.

On a recent ride, with my Radbot and Viewpoint lights blazing by day, I stopped at the local post office on the edge of town.
