Elenco Resistor Substitution Box RS-500- quick teardown

[reagle]

Bought this thing on Amazon for $25, figuring it's not a calibrated Decade box, but it's also 1/10 of the price.
Here is what you get for that:

A fancy handle
Lots or 1% resistors and switches
All parts are soldered, though the amount of solder splashes and solder balls is rather excessive.
(See a nice collection of solder balls I shook out of it)
All resistors are bypassed by default, so unless you remember to leave on switch on you get a nice short across the terminals
Lower ranges see higher percentage of resistance due to all the switch contacts in series.
Higher values are closer
 
Overall convenience- "it'll do" for cases when you just need to tweak resistor value
