Barely worth the money but not too bad if you really need to tweak an inductor value in between E12 values from 1 to 1000 micro Henries.

Accuracy is low (more than 10%) Can only use one value at a time, they cannot be added together.However, if you need a simple device to find the value needed to fit you design then it does the job.

It should be clear that this is NOT an inductor decade box. The inductors are in parallel so it is not truly a 1-1000uH range of inductors, unless you want to determine what set of inductors in parallel will provide you with the value you want.It would be more appropriate to call this a 37 value inductor board.Honestly I can't figure out why they wouldn't just put them in series....
