I bought this based on a recommendation from a co-worker who purchased this at a truck stop. I am so glad that I did. Its like a power strip...for your car! The 3 Edison plugs are spaced just right so that you can fit 3 wall warts, the USB power is a major plus, and the car power port on the other end is of course a necessity. I love the rubber cover for the USB jack for when it is not in use (It is made of thick, durable rubber, and mine doesn't even show signs of wear).
As part of my job, I often have to drive a truck. That being said the cord is long enough to either set the strip on the dash, or the floor. I have never had a problem with heat, fan noise, or power draw. It is also pretty heavy duty, especially considering it doesn't weigh very much at all. The strip has 4 screw slides on the back for more permanent mounting.
My only complaint (Other than not having more outlets, which just isn't practical running off of a car power port), is that the L.E.D. indicating that it is turned on could be brighter.
This item is awesome for long trips, or for when you have to wait in the truck for a long period. I would say this item is a must for truck drivers, long trips with kids, or those people with tons of gadgets. 5 out of 5, I would not hesitate to buy another one.
