Do balancing tools require any special knowledge or can you learn everything as you go along? A favorable option has come up and I need to decide quickly. Frankly speaking, I don't have time to study, but I need the tool in my household.

Any balancing tool requires a steady hand and an understanding of how it works and what it's for. However, I can't say that it's wrong, complicated or requires you to be a logical genius. If you want, you can learn right in the process, starting with balancing the simplest devices and carefully monitoring the result. It would not be superfluous to watch a video from a pro.
