I have a drawer full of old cables and I found out some of them were of a vintage and would not pass modern high speeds. I bought these cables and speed tests show these cables will run high speeds.

Out of the 6 I bought, 3 of them were bad. I?d lose link randomly. Monoprice customer service was great. They got me replacements out immediately but I was a little disappointed because in the 15 years I?ve shopped with Monoprice I?ve never had a defective product.
