Too bad it didn't work.

This was a very good attempt at the closest assignation attempt on Adolph Hitler.  The executions were dragged out for holywoods effects.

I would have liked it if worked, have seen ones that do -- it was not wired correctly and no way to fix, no paperwork included in box to return it and too cheap to worry about. I will buy another one locally, so I can make sure it works before buying.

Failed to work..maybe just a bad one, looking at other options

It would have been great if it worked.  After a day of use, it wouldn't work.  Went and ordered a new one for the few dollars more.

Nice product (I have an older one)and nice price.  Unfortunately, it didn't work and I returned it.  No problem in receiving a full refund.

Mine did not work. They are sending me a replacement though, so I hope that it works.

Pretty simple. It didn't work, had to return it.

What a great idea, I thought.  Well, today was the day I finally had the "chance" to use it.  I left my headlights on and was relieved to know that I could just pull out this device and be on my way.  No such luck!  I followed the instructions exactly and IT SIMPLY DID NOT WORK.  Nada, zip.  Why is this product still on the market?  And why did the latest Consumer Reports just report it as one model that actually works. It doesn't.

I would have loved this, but the one I got would not work or was damaged.  I decided not to try again in case it didn't work either.

I never could get this to work. I installed the first one and it didn't work, so returned it and bought it a second time, that didn't work. So I gave up and just returned it. Might just be my bad luck.

I tried it over and over again and it didn't work. I am glad I found my old one.
