Does it work?
I'm not 100% sure if this works?.. I've put it in my brand new car, and so I've obviously not had any bad odors in the car.. Not a smoker, so no immediate results. Still think it looks cool, and the science behind it makes sense. Plus it's cheap, so why not.

Totally not working for me
Its just a piece of electronics that send a purple light and not affect on the odor or dust

smoker's best friend!
haha should have named it "smuggler's" best friend... j/k

but this thing been sittin in my car by a filled ashtray which usually makes my car smell like s***!

Pros: it really does take most light - medium smells/stinks out (anything in air)
I've tried it with some really stinkin pakistani/indian foods which usually make my car smell horrible after i keep them inside for like 30 minutes or so

I've tried it with perfumes!!!

cons: It only works when car electric circuit is connected (most cars dont do this when engine is off and ignition key is out)

it may be small for SUVs

i'm overall happy w/ this thang!

*dont know whats the difference with similar looking item in blue colors from same company tho!

Generally satisfied.
I think it actually works... took the stale odor out of the car... at least that's my opinion

Wow, now that's fresh air...
I've had this for about 2 days and was returning to purchase another for my wife's car. This is the first time I've used something like this, usually favoring something that smells and merely covers odors. But this thing, I'm amazed. I'm leary of something that just sits there, creating no noise, showing no mechanics of it working other than the blue LED being on. But it's doing it thing cause I've definitely noticed odors are gone & air quality differences since having it. And the kicker is, I'm a smoker. So returning to my vehicle (refraining from a smoke...hey, it's a smoking cessation device too!...who knew... :) and the air is C L E A N. I'm amazed. Ok..gotta order...
