TENMA 72-7270 RESISTANCE DECADE BOX, 1 TO 11111110 OHM

I’m a senior electrical engineer and design industrial electronics hardware (35+ years). I have two of these Tenma 72-7270 substitution boxes at work and one at home. They have worked fine for years. To prevent it from sliding around on my desk, I cut a 3.5 x 4 inch section from an old mouse pad and glued it to the bottom.

Very satisfied with the purchase. The unit looks professional and works well. Tolerances within range described. I would buy again

It works great.
