30 customers mention20 positive10 negative

Customers are mixed about the heat of the tool. Some mention that it heats up and melts solder, while others say that it doesn't heat well and doesn''t couple well with the iron. Some say that the tip doesn'’t get hot enough to make the solder flow, while other say that they can't melt the solders as well.

"...They transfer heat fast, even on ground plane pads that seem to take other irons forever. I keep my iron on 3/5 for nearly everything...." Read more

"...This prevents corrosion of the tip, and assists in heat transfer (trust me, it's a noticeable effect)...." Read more

20 customers mention5 positive15 negative

"...The screw ring retainers didn't secure the tips solidly in the end of the soldering tool, the tip was still loose after tightening the ring...." Read more

"...The tip came pre-tinned, and it fit fine with no problems. It has worked perfectly since and has not needed more than the usual cleaning...." Read more

"...I'd give it 5 stars, but it came with a little bend at the tip. Not a bend, but it looks like it might been dropped at some point...." Read more

Tip is a little imperfect, but good enough for me.
3 Stars
Tip is a little imperfect, but good enough for me.
I'm not sure how tight the tolerances of this product are, but mine arrived with the very tip looking like it had either been dropped, or just not ground to the correct dimensions. See picture for details. I was not expecting a needle-sharp tip, but at least a pencil-sharp one that is symmetrical.Definitely not worth returning over, as it will still work just fine for my purposes. But this may be relevant to people who rely on this tip for very precise work. This is my first conical tip, so please leave a comment if this is within the usual tolerance of such tips, and I will revise the 3-star rating.
