I use these tips when assembling a transceiver with fairly loaded boards. The tip fits well between the components and provides warmth exactly where I need it.
I LOVE THE MANY DIFFERENT SHAPES BUT TRY THEM WHAT I CAN, THEY NEVER WORK THAN THE FIRST TIMES YOU USE THEM. FOLLOWED ALL INSTRUCTIONS TO TIN THEM BEFORE REMOVING THEM BUT I ONLY SHOWED A GOOD PREFORMATION ON 1-5 USES
We bought this soldering iron specifically because it had to be better or better cheaper. Didn't work and took forever to solder. Well, after I bought this little tip, everything changed. Works and great price.
