Good value and functionality. I’ve used your instruments on multiple aircraft thru the years with no issues. These are a nice upgrade over the original instruments in most older aircraft.
Easy to install, and the CGR was set up to my aircraft’s exact specifications.
We liked the price and the reputation of your company.
