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

Worked perfectly for testing a fuel gauge

Gooq quality!

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.

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!

This thing is going to save me a lot of time selecting the right resistor for LED headlights in model RR locomotives. It looks quite accurate when measured by my good Fluke DVM.

One of the best resistance boxes around very good Matched with a calibrated fluke and it's extremely close Awesome product

Item as described, excellent communication with the seller, fast delivery.

Worked as intended. Compact and functional packaging. I used it to optimize the loop resistance of a current loop circuit. I would recommend it.
