Amazing
Amazing for the price - these are approaching $$$$ audiophile quality - can handle sub bass with bags of definition and zero mud. Simply a no-brainer - get these while they are still cheap!

Great Catalysts
I bought these for my S-Boston Handwarmer. And they wouldn't work at first - and that's because the S-Boston uses a electric heater coil/wire to start up the catalyst reaction. With these you need actually put a naked heat/flame touching the catalyst for less than a second. This starts off a reaction in the catalyst and it smolders/burns very slowly across the surface and turns from a yellow colour to the fluffy sliver/grey colour - that looks like ash. Once you've done this - it'll work in the S-Boston. That intial smoulder/burn reaction makes the catalyst extreme delicate - so you have to do it while it's fitted in place in the Handwarmer. With the S-Boston I bent the heating wire down a little bit so it touched the catalyst, and fired it up for 0.1 secs. With the petrol fumes- that'll start the initial reaction.
So far they have been excellent - I put in about 10ml of fuel (max 15ml in SB) - and the handwarmer has been BLAZING hot for over 30 hours now. Which is much longer than the original catalysts and much hotter than the originals. So I think the platinum density in these is much higher than the originals.
Highly recommended!
