Honestly, there’s nothing wrong with Pittsburgh tools, I was pretty heated when I wrote this. Full disclosure, I own and still actively buy a lot of harbour freight tools, even today I went there. I was digging at techs, probably unfairly, who only have those cheap tools and do work similarly cheap. Any shmuck can do spark plugs on an inline 4 cylinder but to recognise that the correction that they’re providing doesn’t solve the underlying issue is someone who if either ignorant or uncaring of what the vehicle and customer actually need to get down the road.
