Well made and comes with a great case
Product was very well packed, and started on its first press. Works very well on normal shrink tubing, takes a little longer on marine connectors while on high. Only using it for the indirect heat because of the portability of gas, and the reliability of the product. This takes only seconds to warm up. 100 does a great job, and if you want a little more umph get the 200 for efficiency with a larger heat tip for better airflow around the splice.

Well made, although a little bigger than I expected.
This made in Japan butane soldering iron is very nice. I got this since I was interested in getting the Weller Pyropen, but wasn't willing to pay a premium for the Weller name for the same iron. This is very well made, love the visible butane tank, the push-button ignition, although I think I'm still more comfortable with a good old Portasol Technic which fits my hands better and has shorter tip to grip distance. The Technic is getting pretty old though, so I'm getting used to this iron.

Good buy, highly recommend
Easy to fire up, good temperature control, holds good amount of fuel and won't die in the middle of a project. Highly recommend.

Sold build works great for delicate low current wires
Deserves a 5 star from my side . Even in the lowest setting flame doesn’t go . Fast heating and portability where there is no ac voltage source . Like a gas station air/vacc m/c

Its definitely on the expensive end of portable butane soldering irons but the quality is unequaled. Excellent fit and finish with very good temperature control (tip: use a thermometer to get it dialed in). If you have to occasionally do soldering and shrink tube in the field then this is the tool you need. Compact and comes in an adequate case, though you can get a tip cover and carry it as-is in a tool bag pocket easy enough too. Replacement tips are not inexpensive but also very high quality - I've yet to replace mine, even with moderate use for a cpl of years!
