Question: Country of origin of this product?
Document: A quality product that is the choice of everyone taking my stained glass course.It is the choice of our instructor which says a lot.Looking forward to many hours of usefulness in producing my creations.
To me this is the best Iron I have ever used. I use it in cars and on circuit boards. Does the job with no problem.
This soldering iron worked great. Got hot enough to do the stain glass projects with no problems. Love the iron!
This is definitely the best soldering iron on the market,  It has a temp selector and it holds the temp selected with no problems, The only drawback and it is a very small drawback; is most of the instructions are in Japanese! but there were pictures so even I could figure it out. Used this on my first stained glass piece and it was soooooooooooo easy to use. So don't waste your money on other brands of soldering irons buy the best first,
The iron failed the first time I used it within 5 minutes. I tossed it out and ordered a cheaper more reliable iron
The heating element went out in three weeks.
The best soldering iron in the World!Needs to buy more tips and sponge, and you don't need expensive soldering station!
The Hakko soldering iron heats rapidly, is controllable and I'm happy! The cord does not bother me and the iron does just what I need..
One less star for a bit slow building up to melting a cross joint on lead came, so I guess I need more power at times. Makes slight pulsing sound. LED informative. Excellent temperature control.
I love this iron. Very smooth, cleanable and love the temperature adjustment. Wish I would of purchases it sooner. Great
