The SandSmart circuit board on my Jet 22-44 sander started playing up. After talking things through with Axminster service, they recommended a replacement circuit board. It fixed the problem - at a price - £120+
This morning the Jet AFS-1000B air filter started playing up. Low speed - just buzzed and motor turned slowly. Middle speed setting - spun up nicely. Top speed - no significant increase in speed and buzzing in the background. Replacement controller diagnosed. That'll be £64+ please.
Now it's not as if either machine is on 24/7 - both can go for days without being switched on.
The fact that the AFS-1000B controller is out of stock suggests to me that they must fail quite often.
My mains supply is clean.
So on this basis would I buy Jet again?
Simple answer - No.
