All resistors are squeezed into a very small package. They are not sorted, so you have to start with that. The problem is that the values on the card are not always visible. It then tries to read the color code on the resistor. But this reading is difficult because the background is blue and the color bars are not very legible, and was quick to confuse 2 colors. So this is finally a customized ohmmeter. Conclusion: not very convenient.
