My Go-To Soldering Iron
This has been my go-to field soldering iron for the past 5 years. It's reliable, heats up quickly, and has handled countless low-voltage and electronics repairs without any issues. The included case keeps everything organized, the build quality is excellent, and it feels comfortable in hand during extended use. The adjustable flame and multiple tips make it versatile for a variety of jobs. A quality kit that's well worth the money, and I'd definitely buy it again.

My husband has gotten a lot of use out of this
I actually bought this for my husband, and it's become one of those tools he reaches for all the time. He likes that it's cordless, heats up quickly, and comes with everything needed for different projects. It's been great for motorcycle wiring and other small repairs around the garage. He's been really happy with the quality, and I'd definitely buy it again if it ever needed replacing.

Update: Great customer service!
I increased my rating to five stars from one cuz of great customer service. After I emailed the manufacturer explaining my problem, they got back to me the next day. After answering a few questions and sending a photo of the serial number, they sent a whole new unit to me and a prepaid label to return the old one. The new one works as it's supposed to, so I upped my rating to five stars. The LX-770 is a really nice torch and soldering iron for a great price. It heats up quickly and burns for a long time on a charge. The kit includes a number of useful soldering and other tips too. One thing you should know that isn't on this Amazon page: the company says only 3X-refined and higher butane should be used, not just "premium" or "high quality" gas. (You can find up to 14X butane out there; I never knew there were different kinds.) But the impurities in regular butane will cause it to not work well and will damage the torch, the company warns, so buy the 3X or higher stuff. It's a bit more expensive, but not much.My original review:This torch had so many good reviews, I really expected to love it. And I did, for the first two days. I planned to use it mostly as a soldering iron, and for two small projects I tried it on, it was great. But then today I was using it to solder some resistors and wires to LEDs. And when I was using it, or when I set it down, it just would stay lit for a short time, and then go out. I could still hear the gas flowing, but there was no flame and it got cold. It would relight, but then the same thing. This happened over and over again, so it was not a fluke. I tried pushing the lock button as far as possible. But the only way I could use it was to keep and hold the safety lever down with my thumb. Which I am not going to do long term. (I am using high-quality 5X butane.) My only choice is to return it. Although I like the design, I am reluctant to buy another Lexivon because of this experience and will probably try another brand. So disappointing!

Good tool but tricky to fill
I have a mobile auto repair business so this is very handy when needed. It has a pretty fast heat up time, it's pretty light easy handling and is especially nice not having a power cord. One thing though is the butane fill port needs a special adapter to work with most butane fill bottles. I am still looking for an adapter that will fill without letting gas escape. I get enough in to make the tool work but it's still a bit of a pain. The case with all the different tips is really nice also.

This is a great solder tool.
Get this one. Has good safety feature and works extremely well. I use it a lot for solder butt connectors. Price is well worth the quality.

Worth the Purchase!
I RARELY ever write a review in the 2+ decades I’ve had an Amazon account. But, this soldering iron multi-purpose kit earns a review! It’s so cool!!! It works very well, and heats up quickly, and the locking-switch feature is a must-have for soldering and what not. It’s easy to refill, has a great fuel capacity, has a great flame strength, and installing the different tips and accessories is a breeze! I’d highly recommend this item!

For price, as good as Snap On's!!
First use I compared it to Snap On's $150 one. This has what you need. Locking click tab for igniter is extremely annoying but there for a reason. Case is made well, and tabs are also made well. Easy to use if you have used one before.

Toolboxust for the engineer
Well built and designed. No issues with filling, as with other brands at a higher price. Quick to heat up and more choice of uses.Can't actually fault this unit, used a few in my time but this definitely ranks in the top few. Comes in a good case to keep it all together, cover can be put on for safety when still warm. Would highly recommend as a toolbox favourite.

用途ははんだ付けから簡易バーナーまで幅広く対応できる
はんだのみならず、付属のアタッチメントを変えればエンボスヒーターにもなり非常に幅広く対応出来ます。バーナー自体の火力もかなり強いため、アタッチメントを取り外して火力を最大にすれば、少し時間はかかりますが炭への着火も可能です。ガスも100均で売っているライターガスボンベで充填可能なので、手軽に利用できます。一度のガス充填でどのくらい使えるかわかりませんが、火力最小でのはんだ付けならばガスは無くなりませんでした。最大火力で炭に火をつける作業を約7回ほど行ってもガスは残っているようなので燃費は良さそうです。しかしながらガスの残量を見る窓が無いため、予備のガスボンベを用意しておいた方が良いかもしれません。これくらいの作業ではんだごて出すの面倒だなって思う人にはぴったりの商品だと思います。

Handig en betaalbaar!
Als je moet solderen onderweg en je hebt niet altijd elektriciteit to je beschikking dan is dit een prima boutje om in je gereedschapskist te hebben. Heeft me al vaak uit de brand geholpen.Prima bout, voor een prima prijs
