Good quality, I have had no failures with these wires.
Excelente producto .
They're jumper wires; What can I say?
Don't waste your time on these.
I chased what I thought was a protocol bug for two days and found out it was intermitents caused by these cables.
Went to a better quality cable and all the problems went away.
First time using all of them and 5 broke.
I bought wires from amazon before and my other ones didn't even break unless I really yanked on it .
