So is it worth $230?
It's probably the best taillight on the market right now. If you've got the $$$ and value your safety and are concerned with appearance, it's worth it.
On the other hand, if your budget does not allow this kind of expenditure, you can make do just as well with my Fred-light-twin-pack, shown in post

Biggest difference is that with the Designshine the women will be running after you pleading for your phone number. With the Fred-twin-pack . . . well, . . . maybe not.
That's all, Folks. I'm outa here. Ride safe!
