Query: works great!

I was concerned that an aftermarket wouldn't work as well as the LG brand, but I have not noticed any difference. I use it in my car (Matrix) that has a standard 120V outlet. I wanted the plug end to be slim like the original so it would still fit in the car outlet. The slim end also works on power strips without interfering with the adjacent outlet.
