If it ain't broke, don't fix it...
I agree with this 100%.
All of my
devices have performed very well for me over the years so I never felt the need to mess with success or "upgrade". Some worked so well for me that I decided to purchase backups to those
devices.
I have a 2nd Juggernaut and another brand new Moon that I purchased 3 years ago that i've yet to unwrap. I purchased the 2nd Moon thinking that would be the
device to fail due to the pushbutton switch and LED (not full mechanical), but nope, it's still going strong and has yet to fail after years of use. I guess the switch really was capable of the advertised 25 amps because it still fires every time.
I've always tried to stick with full mechs to avoid any additional points of failure and so far have never had a failure that typical maintenance couldn't solve. My luck may or may not be due to purchasing authentic over clones, not that I had much choice. Back then, the clones were pretty bad and unless you wanted a Nemesis clone, your options were extremely limited.
