Flexwatt clips vs solder

[The Serpent Merchant]

Actually its just the opposite, a good solder joint will give a near zero resistance connection and does not fail under normal conditions. As for "interference".... what are you talking about? The clips are a pressure connection and reversible. There is more potential for a high resistance connection to form over time on something that heats and cools (expansion and contraction)

Assuming both are installed correctly, are both safe and work? yes, but to say whats better.... soldering is the easy answer.

I was talking about someone who doesn't know how to solder.. IE the soldered joints are bad. I agree that if done properly soldered joints will be better.

Context is important

Unless you Know how to solder I wouldn't bother...
