Works great. Black anodized color instead of the original bronze like pictured. The GEM doesn’t have the OAT probe on the diagnostics page and the troubleshooting process is rather complicated and I did not have the correct resistor to test it. I took a chance swapping the probe out would fix it and it did.

Unfortunately, these fail every 2-3 years. Mine is installed in protected area from elements but I keep replacing these on an about 2 year cycle. I test them on a bench with a 9VDC supply per Insights technical documentation and they are unfortunately dead. Insight claims that they are Durable and long lasting but my experience shows otherwise.
