Your (customer) service is excellent!

Thomas T. from Washington
Piper PA-18-150

Easy installation, lightweight solution. It looks good and is easy to use.  [I chose E.I. because] I needed to replace my old Hobbs meter.  This provided more functionality, allowing me to remove my old digital timer, and EI programmed it to my current airframe time.
