I looked at reviews at it looks like there were quality issues probably 2 years or so ago.
I can't speak to quality, as I was honestly just looking for a cheap set of cables to have available for trips and such, so I'll admit I set my expectations pretty low and was looking for the least expensive option. These fit the bill for me, as they were under $4 once I factored in the $1 digital discount for slow shipping.
