Not as good as the Monoprice brand hook & loop cable ties like this, which are also sold here on PrimeCables. With these PrimeCables ones, the spot where "PrimeCables" is written doesn't have any hook/loops, so fastening strength is greatly diminished there. Also, the hooks/loops on these PrimeCables ones are quite frayed compared to the tightly-grouped ones on the Monoprice ones: the PrimeCables ones are like a bad hair day, and the Monoprice ones are like well-groomed hair. Both brands seem to have similar hold strength when fastened.
