4.0 out of 5 stars Not bad, but could be better
Reviewed in the United States 🇺🇸 on January 11, 2020
In the attached picture, you can see that the device is simple and informative. It is built into a nice plastic case. But... It could be better. Alongside a similar device, it can be seen how this device is missing the ability to disable individual lines, which could allow for the re-routing of input/output in needed cases. Each device has individual strenghts, but most users of devices like this might appreciate the ability for the greater features of a less beautiful design. It is just a testing device after all and isn't meant to be shown to an end user.
