Not affiliated with the company but I have several of their products and am impressed with their engineering and the price they offer. Need a caliper, I don't like digital devices. . I work with European cars (Alfa Romeo) so I needed the metric system, but I also need to use good old inch. What could be better than a pressure gauge that measures both? Brilliant idea well implemented. Great price around $35 (can't remember exactly). Beautifully finished, easy to read graduations and a two-hand dial are cool. Reproducible results and rarely need a zero stop. It would be helpful to have a logo on the box so you know which side is up. After several unsuccessful attempts I stuck a label on the top cover. The packaging could have been a bit better too, as it doesn't quite reflect the quality of the tool inside, or there might be an upgrade option; maybe there is? Great product for casual users or hobbyists. Probably not for prolonged daily use when more reliable and/or accurate instruments would be more appropriate, but at what cost? It more than meets my requirements.
