works excellent, instant start.
works excellent, instant start. push button to lock torch on, has lock out button to stop unintentional lights. very nice torch, i did hesitate as price is on spendy side, but well worth it so far. the flame is not really adjustable down lower, only down side if you need that. it rips full all time.

Love it. But I am not a plumber.
Before buying this on Amazon, I read many of the reviews for the product, including many from seemingly qualified plumbers discussing how to sweat copper and so forth. Let me just say that I have absolutely no professional need for a blowtorch and will not presume to discuss this product's utility in that context. To my layman's eye, it seems very sturdy and has worked well. What I will say is that I have tried a few blowtorches in various settings and this one has functioned flawlessly for several months - including resolving a problem on another blowtorch: the lack of pressure regulation which causes the blowtorch to go out when aimed downward or inverted. Without this feature it is next to impossible to sear steak, glaze creme brulee, or do other things made more fun with a blowtorch that require a flame directed downward. This torch is able to used in any position, including upside down. Just today I did an experiment with my kids to verify that older pennies have a much higher copper content and thus get hot but don't melt, while newer pennies are mostly zinc and melt in seconds. Several reviewers noted that the internal ignition mechanism stopped working after a while. That hasn't happened with mine (yet) and it always lights on the first or second try. You can also light it externally with a standard flint spark igniter - the kind your father or grandfather would have used (I also use these for my gas stove as I'm too lazy to fix the sparker and they are more reliable, cheaper, and last longer than the long-necked butane lighters). If this ever happens to me, it won't affect my ability to use it, but for professional use you can see how the ability to quickly activate and deactivate the torch on selected spots would be key. ****UPDATE JAN 2015**** I try to periodically update my reviews to provide some insights on how a product has (or hasn't) held up over time. I've now been using this blowtorch regularly for about 2 years and it has functionally flawlessly. The push-button trigger still ignites on the first or second try and the pressure regulation continues to let me use the blowtorch in any orientation. WARNING: once you start keeping a blowtorch handy, you are going to start using it on a lot more than you ever imagined.

Fast shipping, works perfect and is the real deal
Ahhh, the Bernzomatic of days gone by. Been using this brand for many years and have always been satisfied. The one that this replaced was easily 8 years old but it fell off my workbench and broke a brass tube so it was time for a new one. This unit is exactly the same in functionality as the old one and it works 100%. Now I'm happy again.

Super Nice If You Don't Get a Dud
I have mixed feelings about this product and other Bernzomatic products. When they work, they're excellent and reliable. But it's not uncommon that you just get duds. I went through two returns before I got a head that worked properly consistently, and that is not the first time I've had an experience like that with Bernzomatic.

Satisfied customer 🔥 🔥
I received this today. So far so good. It is sturdily built and the igniter works well. I’m mainly going to use it to help start fires 🔥 in our fireplace and backyard fire pit, so I didn’t need an adjustable flame and opted for the TS 4000 over the TS 8000. But I would have been happy either way.

The only propane burner worth buying. Cheaper plastic knock-offs like Hot D--il just crack, melt and leak gas. Don't waste your money on others.
