I recently bought four sets of these .008 strings (because EBs was sold out...). Three of those sets have have had the high E become unravelled at the ball end after only one or two days of use.
Never had these kind of issues with any other strings, so my advice is to avoid this brand. Just go with D'dario or EB.
They did sound and feel alright for what that's worth with utterly unreliable strings.
