Cheap price, Excellent unit
I previously had the standard longer fuel tester with the screw driver on it. The needle part was made of cheap plastic and it always broke. This tester is a solid piece of metal all the way into the base. In addition it works better for me because it is wider. I found the sumps sometimes like to shoot all over the place and with the wider can it was much easier.
