Title: Basic and inexpensive, but worth it
Review: This is a simple basic little gauge that does the job well. I bought it simply to monitor engine performance after a engine install and modifications and it has done the job very well. Fast response from the needle and no sticking or jerky motions noticed so far after a few months of using it. I compared the reading of the gauge to that of a much more expensive gauge hooked up directly to the manifold and they read identical, so it's calibration is good. As noted in other reviews, the tubing is NOT included with this gauge, that needs to be purchased separately. All in all for the price you can't beat it, especially if you are just going to be using it for casual observations of your engines performance.
