With a "John Doe" USB 2.0 extension string Unfortunately, I had often problems with disconnects and unrecognized devices.
With these cables is the past.
Due to the very high-quality finish with gold plated contacts and an obviously good shielding I can even run an extremely fast USB 3.0 external SSD.
And I reached easily the technically limited by the UASP housing 360 MB / s.
Even my two Sandisk Extreme 64GB drives running "at the limit".
So I can highly recommend this cable.
From value for money, I advise clearly to double, this will cost only slightly more than one cable.
The single cable is 2m me personally a bit too expensive.
I hope this review could assist you in your buying decision
