Review on 6-Pack No-Clean Solder Braided Wicks for Desoldering - 1.5m Length - Multi-color (1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm) by Justin Reedy

The weave is so thin that when squeezed it just pulls apart and loses its density in the weave causing it to lose its normal absorbency. I bought 6 of these and they end up in the trash. Also, copper doesn't seem to absorb that well, even if you manage to make sure its weave stays tight. Never again.
