Review on SolderFun ET Soldering Tips for Weller WES51, WESD51, WE1010NA, WCC100, PES51, EC1201A, EC2000 (6 Pcs Set ETB ETD ETK ETS ETBB ETBR02) - Professional Soldering Tips for Weller Soldering Irons by Charles Adelaja

I never write reviews but I must warn you sometimes you get what you pay for. I have been soldering with the same soldering iron for over 10 years. These inexpensive jets don't fit my Weller WES51 snugly and have terrible heat transfer. Buy genuine Weller tips and save your money. You can try wrapping the loose part in foil, but without much hope.
