I have had one for a year or two now and it has worked very well. I use it on three suvs and four cars (including a lowered sports car) and it handles all of them no problem. That being said, the HF jack looks interesting.
Thanks RBI! I have the one with the flex spout on it and love it. This will make a good backup. Amazon has some good user pics of ways to modify the funnel to make filling easier...
