6 In. Compound/Cutting Foam Pad (Item#60311) - Fail
Hook and loop fabric attached to the back fell off after only 1 or 2 removals. They'd be ok if it were a one time use as the foam itself does a fine job. I found these cheaper and better quality then HF ones on Amazon.

I work at a place where our welds have to be done within a certain temperature, and we use Centech thermometers.
They get calibrated by our own QA people once a year, and get checked by external auditors at least once or twice a year. Never had one give us any trouble.
