I read all of the reviews, and am convinced that many people either expect a $40 measuring tool to have the same quality as a $500+ tool, or they just like to be nay-sayers, or don’t know how to use it. This is a fine height gauge for $40. I am totally pleased. Of course it needed some calibration (it was not square to the base) but by loosening a set screw and using an engineers square on a surface plate the problem was quickly solved. Regarding the flatness of the base, mine was fine. If there is anything lacking, I would say that it takes some patience to set the gauge to a specific height since it doesn’t have a good micro adjustment feature. Just as you would set a caliper for manual scribing, the same process is required with this tool. No big deal. Learn how to do it, practice, and you won’t be frustrated. I would recommend this product to anyone who, like myself, has a home machine shop working to reasonable tolerances. I don’t plan on making parts to a +/- 0.0001” tolerance since my lathe and mill are not capable of doing so. I do, however, expect to make parts that are within +/- 0.001” and this height gauge is sufficient for that task.

The base on the surface gauge was slightly wobbly as was stated in one of the reviews. I was planning on polishing the base anyway...It took me about 15 minutes with a makeshift surface plate and some 400 grit sandpaper to level it out. After that, some 1000 grit to polish it up and it works very nicely. It glides on the surface plate now. I might go to some 2K grit. The reason for polishing…less wear on the granite surface place. You want the gauge base to glide instead of scrape off the material of the surface plate. I checked the gauge with my 1-2-3 block and got exactly that. 1.000”, 2.000” and 3.000” with the block around 80F. Not bad for a poor boy setup. Consider thermal expansion. At 68F, all sides were shy .001"+-. So maybe the block was ground and measured at 80F, dunno. Repeatability was good.

the quality is higher than the price. The gauge is well made and proves to be accurate. For doing small projects at home, I am very happy with it. On top off that the batteries can be bought anywhere. This was a consideration for me. I would buy this tool again.

Very good quality, nice heavy base and very flat on the surface plate.

Acceptable design, but base is a little light and can move during measurements. I would have preferred a magnetic base. However, I found the indicator to be easy to use and very accurate.

Works great for the price, exactly what you'd expect.

great but needs a magnet under base

The must have made changes. The bottom of my guage is ground flat no need to do anything. Work great for what I needed it for a fine tool for the price.
