Audio Horizons fuses.... won’t buy them again...


I’ve bought 5 Audio Horizons Platinum fuses a couple of months ago, for my amps, speakers and DAC.
Three days ago, coincidentially, the 5A fuses on my mono amps (Rogue Apollos), blew at the same time on start up. Replaced them with the OEM fuses, and everything works again.
I have a very good electrical installation, with independent lines for each amp, a no surges or anything strange occurred. My speakers, Evolution Acoustics MM3s are always ON, and nothing happened to the fuses on them.
I emailed Joseph Chow inmediately and his response was to send the fuses back to him (at my cost, I live in Ecuador...), to repair them for $70/each, plus shipping.
I have paid $138 for each fuse in October, and no warranty?... what a shame!!!
Won’t buy these fuses again, NEVER!!!

Once again, an exact copy of the email that I’ve received from Mr. Chow:

”Hi Leo,

That's weird, no sure if the storm around your area cause the power surge.
Is this happening right after power up?
We see less than 0.01 % rating failure in our sales record and we only provide one month warranty.
However, please check the current rating and either slow or fast blow in your original stock fuse.

We can reworking your fuse once it return and cost $70 each plus shipping.

Happy holiday! “

I know but got one these fuses and can’t find anything regarding directionality and was hoping someone will know. Can’t get through to Audio Horizons either.
