This Groupon special caught my eye and I ordered 2. The lights arrived fairly quickly and looked OK.

I discovered that on one of my bikes that the rear rack interfered with the laser lane being able to project to the ground, so I gave one to a friend to separately evaluate the light.
My pros and cons:
Pro: Bright when using fresh batteries, 7 settings for rear LED - continuous or combinations of flashing or sequential on / off of the 5 LEDs; laser lane, 2 settings either on or blinking.
Con: Seat post clamp not strong enough to keep position constant when going over a sharp bump; manufacturing defect on one seat post clamp - kept from full seating of light into seat post bracket until I fixed it; uses 2 AAA rather than AA batteries.
Sarah's evaluation:
Positive things: lots of light settings, easy battery type for replacement, detachment feature to prevent theft.
Negative things: it would be nice if the loop attaching to the bike seat was adjustable, since mine was too loose. Also, would be nice if it had some kind of rubber like material to prevent it from turning/moving while riding.
.......
I installed my tail light a couple of weeks ago and was surprised today that it wouldn't turn on. Used a multimeter and discovered that when my unit is off that it actually draws 2.7 mA.
When the laser was on continuously, it drew 34 mA and ~20 mA when flashing.
The 5 LEDs drew 16 mA when on continuously and ~8 mA when in the other
settings.
I will be pulling the batteries out when not in use and likely modifying the light to run off an external source with a separate on / off switch and likely adding a support to keep the light from changing its angle setting.
Overall evaluation:
Good idea for implementing laser projected lanes, but not so good implementation,
