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!!!

30 days is what it takes shipping to Ecuador...
Bad customers service, to say the least.
Increasing the amp value of the fuses will be dangerous for the amplifiers, don’t you think? I will always prefer to protect my equipment, not the fuses.
Sometimes, you have to make EXCEPTIONS, just to keep clients happy, and replacing a pair of defective fuses wouldn’t have been a big problem for Mr. Chow...
By the way, the OEM fuses are working perfectly.

Uh, the clock starts ticking from the time you get the fuses, not when they’re shipped. Hel-loo!

If it ain't broke, don't fix it!

Are these fuses UL listed? If not, you may be risking more than just a couple of nice sounding, but expensive, fuses.
