I live in the high rockies, the ice box of the nation, where the night time temps frequently dip into the -20's and lower. I don't drive all of my cars, all the time, and sitting without running in that cold kills batteries.
I bought three of them: one for the audi road trip car, one for the F-250, and one for the SAAB c900t. ALL of them start very strong now, anytime that I decide to run them. All of them get started once a month (when the temps get into the 20's). The SAAB is my main driver, but at those temps, the battery drains down if I don't drive it for 3-4 days. Now it fires up every time, no problem - I just leave the cell plugged in and laying on the dashboard.
The cord isn't quite long enough to get outside the Audi car cover to where the sun is, so I simply spliced the power line with heavier ga. wires (heavier than the existing ones, to reduce voltage loss), and hung it in the garage window - works great.
Unit appears to be well built, and compared to others I checked out before buying these units, the price is right.
In the summer, I'll use one of them to keep my camp trailer battery charged up when not in use.
Like it says, it won't do you any good unless the juice can get to the battery - so, with the ignition turned off, push in the cig lighter to see if you have power, or plug in your favorite mobile device...if you have power it will work great. if you don't have power to the cig lighter outlet with the key off, you can always utilize the included battery clamps, and clip it directly to the battery and "skip the middle-man". This might not be convenient, but works just the same. On my car, I simply re-wired the extra cig lighter outlet I had previously installed so that it's always hot.
I would not recommend re-wiring anything in your own vehicle unless you know what you are doing.

Rated 1.0 out of 5.0 by dontknow BIG question?
I gave this product a poor rating only for this reason:
I have an electric 2amp trickle charger that can just be plugged in and go. It works great. Plug it in, it shows yellow if charging, green when charged.
The solar is a great idea is great, I thought I could do the same thing. However,There is nothing in the directions that tells about over charging, or when the battery is fully charged. I am skeptical of frying my battery. Whats up with no info on this? Its a big deal !

Rated 3.0 out of 5.0 by Mike This panel does not have a controller
This controller is well made, good size(fits everywhere). but the main problem is, that its too good.
Here in N.California , in the noon day sun, I'm getting readings of 22Volts ..and that boiled my battery.
So if you live in the sun you need a controller on this panel...to protect your battery from its output
No controller and your battery will be toast, first time you use it in the sun...there is nothing in the directions to warn of this expensive possibility.
Its not plug in and forget!
So be warned.
