Product review (2 stars): Worthless
I've had this vacuum for almost a year, but I'm reviewing it now because until this week, I haven't really had to use it more than a couple of times.  Because it has a plug that connects to the cigarette lighter, I couldn't use this vacuum anywhere but for the car.  Since I like to multi-task things, I bought an adapter so I could use this in the house also.  My car has dark carpet and seats, so I couldn't really tell how well it was working then.  It wasn't until I started to use this vacuum inside the house that I could see it was BARELY picking up the dust on the hardwood floors.  It was only for a light dusting task, for a quick pickup, not a major vacuuming job. It could not even pick up a piece of paper the size of a dime!  I tested it with my hand under the nozzle to see if it was suctioning, and I could only feel a light breeze, like from an electric fan.

I gave this one star for the clean smell - no dust odor, but probably because it was not sucking up any.  The other star was for the price - I bought this when it was on sale here on Amazon for $9.99.  I guess I got what I paid for, which is why I'm back on Amazon today to look for another handheld vac that hopefully works.
