poor thermal protection
I have now replaced this unit three time due to the nose piece melting and failing i have tried repairing it but lack any compound that can handle the heat. Need to be designed better.

Well worth the money
This soldering iron replaced my butane powered one that I have used the past 6 years on my service truck. I wish I had gotten this sooner, it will heat up really quick and at only 90 watts it doesn't seem possible. I have used it repairing circuit boards and soldering #12 together.

Good for portability
I have found the iron nice to use, lots of power and heat recovery, a little heavy but that is to be expected with a cordless iron. My two big complaints would be I would expect temperature adjustability in something this size with the amount of electronics inside. Second, very disappointed the made it with proprietary tips. They only have a point and a chisel tip and both are pricey to replace. All other tips I have tried put pressure on the ceramic core, clearly just a ploy to force you to use their tips.

Best tool I’ve purchased in some time.
If you use this for what it is intended for, it’s a fantastic tool!! The little details make the difference. The light, the drip guard, the adjustable angle, all wonderful. Super fast cycle times, low battery draw, hot enough for 12 gauge wire, can’t say enough.

What took so long?
to the guy that posted the one-star review show me where you can get a battery powered soldering iron that works this nice you can use all day long and not have to put batteries in it. It works best when you put the 6 amp hour battery in it you can do up to like A 1? wire like a battery cable on a car battery it will solder it. And why the heck would you use anything but a Weller lined condition isolated soldering iron station on a circuit board makes no sense. Keep the tip clean and snug. Heats up in 20 seconds.

If you solder in tight places, this is a must
This tool is the best cordless soldering iron I've used. I have disliked butane ones because they tend to burn either other wires around it, you or sensitive plastic around where your working. I've been an aftermarket technician for about 8 years now. Working in tight places where can get a bit tricky with the size of the tool, but that downfall is outweighed by the usefulness. No need to refill constantly, or exaust to worry about. I would recommend having 2 batteries because it does chew through them pretty fast. Heats us very fast, ready to solder in about 30 seconds. Overall a very handy tool that works well.

Very Cool Tool (Figuratively
This tool heats in seconds. I like the led light that indicates when it is hot, it also stays red when you turn it off to let you know it is still hot. I also like that there is no heat exhaust like on a butane soldering torch. I highly recommend this tool.
