No way I could afford one for each device on my retired budget.
How many devices you have that you are able to swap the fuses on?
The reason I am asking is I can only do this in two of my devices. And I have more than two devices. And the two devices I can do this on, getting the Swiss Boxes, makes a big difference. For a few hundred dollars. However, I do realize that if your system is already $free ala Mahjister style, paying money for such Swiss stuff does not make any sense
