Dimension:170 * 135 * 72mm, Weight:Approximate 460g, ONE Precision Variable Decade Resistor Resistance Box Note: The resistance box should be placed in shelter room, the air temperature +10℃~ + 40℃ , relative humidity below 80%, should not contain harmful impurities which can cause corrosion. Rotary resistance box for the DC circuit for use adjustable resistance, has a lower value of zero resistance, are all the most commonly used laboratory instruments for schools, factories and research units for electrical measurements and other experiments. When you test with the item, please make sure the voltage is under 5V, and the current is under 50 mA.The power is 0.25W When the proper use of resistance box to rotate the knob in each group, so that the contact resistance is stable and reliable.The maximum allowable current value of the resistance box in use should never exceed the specified. When only a small change in resistance, then wire to the "0" and another small indication terminal, can reduce the resistance inside the lead resistance.

J**.
Maybe a box for future project...
But a piece of crap for a decade box. While testing I could not get ANY of the resistance to measure under 10% of what I had set it at. Some were out as much as +-60%.

Cheap
Tolerances where terrible. Potentiometers cheap and inconsistent resistance. Best part about this product was the case I can reuse for future project.
