Review on 📏 Standard Thickness Measuring Gauge - Stainless Steel Universal by Keith Desjarlais

I was looking for two characteristics of these probes for my application.1. Corrosion resistance 2. Non-magnetic. They advertise "high quality stainless steel" but have a strong magnetic attraction when close to a magnet. I wish I had read the reviews beforehand or let them advertise this moment. Also, I should have been more careful when they advertise that they lubricate the sensors with oil to "prevent pitting and corrosion". Her words. I work in mechanical engineering and have never heard of "high quality stainless steel" which is magnetic and corrosive. I would prefer that they advertise the specific class they are using to avoid such confusion.
