I have had my autometer boost, egt, and oil pressure gauges for over a year now and they still read fine
The autometers are a budget gauge and will work fine, the defi and greddy gauges are leaps and bounds ahead of autometer in terms of build quality (all autometers I have are accurate but they are just "cheap" with the faces wanting to fall off and such) and "bling factor" but thier purpose is the same, just quite a price difference for a gauge that mainly just looks better...
