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

Dear miko71, I think that you are disparaging Ecuador... Am I wrong?
if you read my original post, you can see that the only fuses that failed were the AH ones.
When I paid that kind of money for a fuse, I thought I was buying QUALITY, not just audio quality. 
The quality of the product was bad, but customers service quality was AWFUL.

An Audiogon member just brought this thread to my attention. I want to explain my approach to handling the situation that started this discussion.

1. The customer reported that fuses in both amps opened (that is, they protected) at the same time when the amps were turned on. Two simultaneous failures indicated that some event - power surge or other - at the customer’s installation had occurred. The fuses were exposed to some force outside their operating range and they worked as expected - they protected.

2. The warranty period had expired. I offered to replace the fuses at a reduced price. I asked the customer to return the spent fuses because I wanted to inspect them to confirm the report.

There is nothing more to the matter. Unfortunately, the customer has said he feels ill served by the warranty policy and my offer to supply replacements at half price outside of the warranty period. I regret that he feels so. I tried to accommodate him in a situation that has not occurred before.

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! “

Are these fuses directional? If so, which way should they go in?
