Works great! installed flawlessly on my Bonanza

Installed in place of previous thermometer - same diameter hole - had installed in probably less than 1 minute. Previous Thermometer was digital and needed two batteries and was not always on. I much prefer the analog - always on, no batteries and shows both Fahrenheit and Centigrade temps. Perfect!

It works. It fit in the old hole. It was easy to install. What else is there to write about an analogue OAT gauge?

Easy to read, and shows temps accurately.

Manufacturer specifies accuracy of +/- 5F. Testing my new one found it to read about 2F above actual, as compared to an accurate digital thermometer at ambient of 70F. About all we can expect from an analog thermometer. Order processing and delivery pretty standard for Spruce and USPS.

So far it seems fine. Looks to be a good quality replacement for the original OAT gauge, which was also a Scott, but the plastic over the dial had become opaque making the dial hard to read.
