Great product. So easy to read compared to the originals.
Love the situational awareness that the CGR-30 Combo gives me. Easy to read and understand displayed information.

The installation was straightforward and quite easy. Reliability and accuracy far exceed the original [aircraft’s] oil pressure/temperature systems. Also, the price was about a third of the cost to replace the gauge cluster.
