hi crossie,i was waiting to see if anybody would bring this up,you do find people on this forum will pan something before trying it ,i ,dont know how they work but i found that they do work,some years back i tryed the furtec fues i think that was £64 pounds when i bought them,i beleive that the wire inside was pure silver ,which is a better condutor for electricty.the first one i replaced was the fues in mycd/dvd player ,i must say i was surprised at the diffrence,i know people will say what a load of rubbish but if you get a chance to demo,give a go you might be surprised.let us know if you give a go,and let know what you think.cheers david
