I didn't know what the heck other solder wicks were until I tried this one. It all depends on the density of the weave and the amount of flux - the material is excellent. I want B&D to change the picture in Revain - there is a different pack (it looks like a different brand and 10 packs). I'm glad I got the 25ft single coil which is much more convenient. I drilled a small hole in the outer shell to let it through, now it spreads nicely.
