GME RD-300 Resistance Substitution Decade Box, 7 Decades Range, 1Ω to 11MΩ, 1% Accuracy, 1-Watt Rated resistors, Designed in The USA

The build quality is above average and all values aligned with what's marked on the device. Not a bad price considering the quality. I must admit that this one surprised me. It's built even better than what I was expecting. Pretty nice for the money.

Need this for work , wow this works great , a great tool for substatuing fir transducers

A well made unit that I find handy when testing electronic circuits or checking meters.

It's a nice quality box. Sturdy box, nicely laid out. Switches work well and feel good (not cheap like some boxes) Accuracy is very good. 1W rating is very handy - not needing to baby it like a 1/4w or 1/2w unit. Binding posts are kinda cheesy. No test leads. A bit pricey but at least it's decent and sturdy.

I really love this tool and the quality is great, plus it is USA made product 🇺🇸

Bought this for troubleshooting modern accessory circuits that are PCM controlled such as cruise control or windshield wiper circuits. Modern circuits are using simple on off, but rather different resistances on the same wire would indicate different inputs, such as cruise control accel, versus cruise control decel is simply different resistance readings on the same wire to indicate what function the driver is commanding the PCM to complete.

I returned mine. Switches can get stuck "half on" and it is not obvious. Whole thing feels very cheap. All the weight is in the rubber sleeve, which is removable and also stinks like cheap rubber. No QA test result, just a printed word document. I could 3d print a box like this and put the whole thing together with better resistors for much less money ... not worth the price.

Decent R-boxes have long been in the hundreds of dollars, prohibitively expensive for little guys like me... up to now. I got this box. put my Fluke 80 on it, and it checked out on all the values. Very nice. The 1 Watt rated power is excellent as it will avoid a lot of inadvertant blowing-out of a value. Darn good R-box. Thanks GME!
