Review on Apex Tool Group MT1 Soldering by Draven Louton

This item is supposed to be MT3 and 4mm for Weller SP23/25 soldering iron. My SP25 iron uses 3mm = 1/8 inch tips! If I ever buy another soldering iron, it will be one with well-defined tip sizes and easy access to replacement tips. Questionable information from the manufacturer of SP23 and SP25 irons causes double bitter disappointment. B- where.
