So I purchased a set of Testo 557s last spring. I only used them when I really needed fine tuning. I do supermarket service and they were super handy.
Thirteen months later, they're dead. And just out of warranty by a month
I am beginning to lose faith in Testo products.
I've previously purchases a Testo 410. Dead out of the box.. The stupid wholesaler wouldn't even refund me. The only solution was to ship it out for repair.
My first set of Testo 523s were great, but they died after two and a half years and couldn't justify the repair bill.
I'm bailing on Testo. What digital gauges do you fellow market techs recommend?
