I'm not bashing it. I just don't trust it to be superior to a genuine Bussman. They use the hype code word "nano" with no technical explanation of what I am buying. The package them in individual plastic boxes with foam inserts, special stickers and gold plate, and it still only costs $5. I'd sooner buy the gold plated genuine Bussman fuses without the nano hype from UK. But that wouldn't give me the ultimate fuse because it is still an aluminum Bussman fuse like the stock fuse I already have. So I would rather buy Synergistic Research fuse from American company that I know and trust and who explains why it is worth $80, or a SINE fuse from Germany where their TUV agency must quality test every export product.
Why would I spend $80 instead of $10? I seek value, not a quick thrill or just quenching my curiosity. If fuses matter, then I want the best fuse there is, it's only $80 for such a huge claimed improvement. $80 is worth that, if it's true. And I wouldn't consider buying any upgrade fuse if I thought for a minute that there was a change that my equipment would pop it.
