Best I've found - a bit pricey tho
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.

Wow such a deal!
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!

Way overpriced
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.

Well made product, does the job!
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.
