Good little lighter overall. Not as hot so its good for soldering automotive wire connections.
I am overall happy with the lighter. It does not seem to have a way to lock the flame on so that you could release the trigger and having the flame remain on.

Junk
Came without fuel, took me 2 weeks to get fuel then the igniter didn’t work. Forgot about it , was going to return it, but too late now. Never buy!

Turn a low quality lighter into a decent torch
What else can I say? Turn a low quality lighter into a decent torch. And it comes with a refillable lighter / fuel container. I ordered 50 cheap lighters here on amazon for $11 to pair with this.

A nifty tool
When I saw this tool and thought about ordering, several of my co-workers were also intrigued and so I purchased multiples. Everyone likes theirs and I like mine. So lets look at the product shall we? First: The disposable lighter Not just any style disposable lighter works. The Scripto or Toaki lighers work. My Bic didn't, in fact the SODMJ300 broke the gas release tab on my bic. The torch DOES come with a refillable cartridge shapes like a Scripto lighter with the flint and wheel removed, so you don't necessarily have to have a disposable lighter ready to use it. Second: While other reviews say that the torch requires two hands to work, I found that I could operate it quite well with just one hand and my hands are hardly large. I can just use my thumb to pull back and down on the tab on the back and it works! Third: Despite the name being "Solder-It" It does not solder very well, and at 2400°F it was expected not to work well. The solder flux the tool calls for does not flow well, and the high temperature tends to do more damage to the wiring harness than I want. This is NOT a soldering iron. I just tried it because it claimed it could be, but on nothing I expected to actually use. DONT TRY SOLDERING WITH IT. Finally: It is a butane torch. Thats what it is, don't expect anything else. It does one thing well, it puts out a hot torch flame like all torches. It just happens to use disposable lighters so that if you find yourself in a place where you can't use a refill cartridge, you can pop in a lighter (which you could find anywhere, even bumming one off a co-worker). We have been using ours for everything from heating shrink-wrap over cables to de-icing our car doors so we can open them this winter. We have even done some "emergency welding" (though it does a poor job at it) that held up to when we could get it properly repaired. One co-worker even lights his cigars with it! Thats why I gave it FOUR STARS. It only claims to be a butane torch that uses disposable lighters and thats exactly what it does. It doesn't work well enough to rate 5 stars, but this item has found its way into our travel-kit toolbox.

Torch great! Lighter crap…
Been looking for these torches for a while. Bee using them for 15+ years and then they disappeared. Found them again! The quality of the torch is great! Unfortunately the the refillable lighters failed immediately, the valve where you refill the butane does not properly close and the butane leaks out. Very disappointing. Easy fix, just ordered up a package of refillable lighters from Amazon. Out of 4 lighters 2 of them failed in the same way… Geiss I have to play numbers game and order more lighters in the hopes that one of them will last. Unfortunate as it’s very wasteful and yay more plastic junk in the world… Recommend the torches but the lighter part is crap!!

Not as good as same model I purchased 20 yrs back.
I used iRoda torch back in the 90's, cheap, convenient and always worked well. After 20 years I decided to purchase this one and the experience is different. First of all it does not look as well made as its predecessor, obviously everything even simple tools nowadays become flimsy and just unreliable since manufacturers figured out low quality is another key to sell more product as they brake. The one I just purchased has no longer smooth edges and there is no grainy texture on the outside of the body which was helping to grip and hold the tool. They also replaced convenient side safety slide switch with something that is underneath the trigger lever, so in order to engage it I have to use another hand which is just ridiculous. The tool works but I am not as happy as I used to be. You would think tools gets better in time as their design improves based on customer experience. Well, this was a case back in the day, but not anymore. Most of today's tools look, feel and act like cheap knock offs. Shame.
