Burner control is accurate.

This portable burner is amazing.  The control know for controlling the flame is accurate vs the Asian grocery store bought burners.  Used this indoors and it works well.  Highly recommend this japanaese engineered product.

Five stars for now.  I just did a test burn before it is used this weekend.  Tested a pot of water, 3 cups.  With a high burn in windy conditions with gusts up to 12mph the water simmered in 2 minutes and boiled in 3 minutes. Not sure how that compares to say a Colement ~11,000BTU per burner, but Im happy.

The insta-light light the fuel first try.

The only thing I don't care for, where I would give this 4.5 stars (but I cant), is there isn't a secure place to put the fuel line from what I can tell.  So I kept the twist tie and use that to secure it the grill when packing it up.

I'm very happy with the high-output burners on this stove.  The burner can still be turned down plenty low.  For the price, this stove can't be beat if you're looking for a high-output model.  My only complaint would be that it is quite thick, but the extra heft does make it feel very sturdy.  The built-in igniter is great too as you don't need to carry matches or a lighter.

When I unpacked the burner there seemed to be some sort of white paper or something stuck to it in a few small places. I was able to get most of it off.  I turned it on and let it heat several minutes. It heated very fast and seemed hot enough. Then it cooled down reasonably fast.  It seems to be very nice for the price and since I don't use a burner very often I'm sure this will work very well for me.  Being able to purchase this on Amazon is very nice as it saves me running from place to place to try to purchase one. Actually I looked on line at Walmart and a very similar burner was over 3.00 more expensive. SEVEN MONTHS LATER: This burner is still working very well. I use it to boil a big pot of water for spaghetti and doesn't take any longer than it would on a regular stove. I don't use it every day but a few times a week and am very pleased. I am going to order another to keep on hand in case this one goes out on me.

I bought this thermometer to check the temperature at various locations on my wood burning stove. This is critical on a catalyst type stove to make sure that the catalyst is working properly. Sometimes I can get two different readings at the same point which tells me that this thermometer contradicts itself. I found that if I hold the trigger to get a "streaming" reading it seems to be more accurate. The laser function is nice, but I seldom use it. I just get close enough to the target where I don't need it. Overall I suppose I would conservativley recommend it.

Thankful for the safety features of this burner.

It effectively boiled an egg. And boiled the pot dry when forgotten, and exploded the egg.  And automatically shut itself off.

I've seen other reviews complaining a little bit about this burner's safety features, but they are well worth it.  Great value.

Performs as advertised within a couple degrees of accuracy.

Works as advertised. Searing heat is very high. Product arrived a few days early which was a pleasant surprise. Installation was more difficult than stated. The pull-out pin is hard to reach and requires some special hand maneuver and sharp nose pliers to remove. The pin cannot be reinstalled once the burner is installed, which is ok because it's not really needed (even though instructions say you need to reinstall the pin). Overall, I'm happy with this burner and it's working well.

We have been using these burners in our home for over a year.  I have adult ADD, and aside from the peace of mind the safety aspect of these burners provides, these do help me cook better. The even heat distribution and automatic temperature reduction counteract my tendency to turn foods on "HIGH" then forget about what  I've got on the burner when I'm doing other prep work. Foods like sauces, scrambled eggs, bacon, and even fried chicken, are turning out so much better with these burners. NOTE: You ***have*** to invest in heavy-bottomed cookware with these burners. You need a  flat bottomed pot with plenty of surface contact. The thin-bottomed saucepans I had been  using with my old coil burners were too warped to use with the SmartBurners - I had to stop using them in favor of a few better heavy-bottomed stainless & cast iron pieces. Well worth the investment.

I bought this with a battery-powered crackler. After a few minutes, you think you're looking at a wood burning fireplace. Thermastat control allows a steady heat, and it works well in a 400 sq. ft. room. The flame is very realistic down to the embers.

It is what it is. Works as expected. My old burners had pretty much rusted apart and were giving a very uneven flame. This is definitely an improvement. Some people apparently have a type that locks in with a twist or something and were complaining that these burners don't do that. On my stove they just sit in the holes with no locking feature.

I knew it did not come with a rubber gasket, but it would be nice if it did. When sitting on the metal surface of the stove the spark igniter sends an electrical shock through the entire stovetop. I have to be careful not to be touching anything metal that's in contact with the stove (like a metal handled pan) when turning on a burner. This was already a problem as my old gaskets are falling apart. Has nothing to do with these burners. I'll be searching for gaskets...

Once operator head space was overcome the thermometer worked as advertised making my BBQ operation simpler and more controlled. Results off the grill have improved as a result.

It's performing up to expectations and not burning through batteries as some early reviews had indicated. They seem to have that problem fixed.

Just plain works.  Seems to be accurate and can take the heat.

Works as advertised.  Fire burns hot with minimal fuel and boils water with minimal trouble,

The triple burner Mr. Heater delivers excellent heat. It lights easy, but a electronic ignition would be nice. Gas usage is close to the specs listed. My only complaint like one of the other reviewers listed, some of the burners will shut off sometimes for no reason on low heat. Maybe i just need to adjust the thermocouples.

Took only a fews minutes to install and works great. This is the burner for the small burner.
