Has anyone bought one recently that actually works?
I haven’t had luck, and assuming you get a new one that works, I wouldn’t trust them long term.
Best solution I know of nowadays is Classic Quality: https://www.classicquality.co.uk
They sell a mechanical gauge that looks exactly like the original (even the correct PSI which is rare) with an install kit. Not sure of the current prices, but a few years back they were ~$150 + shipping, which I consider very reasonable.
