Hi, I have the option of either an Apilus Junior 3G (still under warranty) or an Apilus Senior 3G, not under warranty anymore and a bit more expensive. (Both second hand, Junior includes a nice amount of probes).
Which one is better? Is there much of a difference between the two? Is one of them more user friendly over the other?
I appreciate anyone taking the time to reply to a new (amateur) starting this journey! (Electrolysis)
