QUIETSTOVE Silent MUTER Damper Cap for Camping and Backpacking Stoves

The Quietstove was a balm for me. Last year I purchased a MSR Dragonfly to accompany my Universal Wisperlite so we could cook for a total of 12 backpackers faster. I love both stoves for their different primary functions, but the Dragonfly is significantly louder than every other stove I've ever used in 45 years of cooking on the trail. Even louder than a butane fueled Jetboil - which I use at lower altitudes for different reasons -(virtually instant coffee anyone?) Let me be clear - the noise of the MSR Dragonfly was not enough for me to return it for a second Whiperlite, but enough that I wished it to shut up and let me drink my coffee in peace. The factory plate over the gas outlet does its job of diffusing the flame respectably but does so with a roar that will literally wake everyone within 100 feet. It was my alarm clock more than once. At least I didn't miss breakfast, right? There's my silver lining.My crew and I used the Quietstove / Dragonfly combination over the next 300 or so miles of backpacking this past year. The Quietstove solved my only inconvenience with the Dragonfly. It rendered the stove silent, well silent enough to allow nearby campers to sleep and to maintain a normal speaking voice while preparing food. The stove's performance was on par with the factory pieces from sea level to 10,000 plus feet. Maybe a few seconds longer to boil water, but significantly more quiet and we quit yelling while making breakfast, much to our sleeping neighbors relief. Also, if your sole purpose is to boil water - the Dragonfly is not the better option. The Whisperlite will win every time in a white gas stove.The Dragonfly is used to actually and directly cook food instead of heating water. Ahhh - real food! On the trail no less!The Quietstove fits into the Dragonfly snugly after a good heating and stays pinched in place once cooled without randomly falling out. I did not need to change out or adjust any parts and the legs folded around the new configuration of the Quietstove without any adjustments. This was important since we often started dinner after dark and in the cold. I can remove the Quietstove from the Dragonfly easily with a bit of torque from my thumb for inspection or cleaning after a messy cook, but I stopped worrying about losing it almost immediately once I felt the snug embrace after a good heating and cooling cycle. My advice - Don't mess with it after it cools. Playing with the parts loosen them and cause them to disappear when you don't want them to. Heat it, cool it, and don't touch it unless you must.I had only one under burn (or whatever they call it when the flame collects under the stove instead of outside the burner where it is supposed to be). This was easily and instantly remedied because I read the warning and instructions before hitting the trail. None of us allowed it to happen again, Knowledge is power - and safety. Read the paperwork.This item works as advertised and for my allergy clogged ears, a blessing. If you have an MSR Dragonfly and don't care for the jet propelled roar - I can't recommend it highly enough. You will hear yourself think again. If you don't mind the noise of the factory oven, don't walk away yet. The Quietstove provides a better (IMO) and more uniform pattern of heat to the bottom of the pan. This allows you to maximize the unique purpose of the Dragonfly - to simmer. The standard diffusion plate did not spread the flame uniformly, which after a major $$ stove purchase designed to simmer, was disappointing. Yes the Quietstove was a pretty penny for what it is, but I believe I got everything I paid for and more. Bon Appetit!

I bought the Quietstove 107 for my MSR Dragonfly back in 2018. It really works, just as advertised. I had no trouble with it until recently, when it started to go out instead of staying lit when I turned my stove up to full power. I reached out to Quietstove customer service last night. They responded almost immediately. In less than 24 hours, they diagnosed the problem, found my purchase record and have sent me a new one, for no extra charge, even though my Quietstove is over four years old.Excellent product matched with excellent service!

Good instructions, just does not work right. If it is quieter, I could not notice a difference over stock. Thankfully the instructions warn you to look for signs the QuietStove damper is burning internally, because it kept burning inside on every attempt to use it. I made sure it was oriented correctly and fully seated but I noticed that no matter how I rotated it, there was always some hairline gaps where the base of this damper met the original bell housing around the jet. I always use a wind/heat deflector but I noticed that when I could get a good ring of blue flames from the QuietStove damper the wind would still negatively affect it despite the deflector. I never had this problem in stock configuration.On my first attempt starting from a cold stove, getting the fuel tube hot is more of a challenge since I do not have the dish of the original flame spreader. I ended up using a piece of cotton soaked with camp fuel which is one more thing I would need with my stove to light it in a controlled manner. With the fuel tube hot enough to atomize fuel, I opened the valve and the QuietStove damper was not putting out a ring of blue flames, instead the metal body was turning all kinds of colors (burning internally), so I closed the valve and let it cool. I tried again when it was cool enough for me to re-seat the damper. It produced a nice ring of blue flames this time so I began to think the first time was a fluke, so I put a pot of water on top and began timing for the rolling boil. Less than a minute on the watch and I heard the sound on the damper change so I pulled the pot off and sure enough the metal body of the damper was changing color from burning internally. I closed the valve and waited for the stove to cool enough to adjust and re-seat the damper again, and started over (also trying slightly different valve setting), but it was burning internally right away this time. Rinse and repeat and get nice ring of blue flames followed by the damper regressing to burning internally shortly after.I am well-versed in using the valve on the MSR XGK-EX (it is very sensitive and flame response has a long lag time). If the QuietStove damper works on your stove, perhaps you are lucky. I have used many other gas-burning camp stoves. This damper makes using my stove the most frustrating and inconvenient experience of any stove I have ever used. I cannot believe I spent a lot of money on this.I wanted comparison times to bring 800mL of water to a rolling boil over the stock-configured stove, but I could never get this to work properly long enough to see what it could do, but it did not appear to be putting off as much heat as the stock configuration.UPDATE: I thought I was going to have an expensive piece of metal I could not use, but Craig from QuietStove took it back long after the return window an refunded my purchase. QuietStove backed their damper.

I was expecting this thing to make my dragonfly quieter but did not expect it to also make it boil water faster. Without the damper, it took roughly 7m30s to bring 32oz of 62F water to 190F in my old MSR aluminum backpacking pot. With the damper and another 32oz of 62F water it took around 6m30s to bring it to 190F. I went back a forth a few times to recheck and it was always faster with.With the stove a full blast, a cheap decibel app on my phone measured 81dB at 2ft without the damper and 65dB with.Looks like a win.

This little damper cap works absolutely great when it comes to reducing the jet sound of a burning MSR Dragon Fly backpacker's stove. It sits in the burner cup and is not attached like the flame deflector that you have to remove. Therefore you need to be careful so you don't lose the damper cap when not in use.

QuietStove Silent MUTER Damper Cap for Camping and Backpacking Stoves,The quiet stove cap is a great addition for the Primus Omnifuel stove. I was considering selling my stove because as the stove comes out of the box it is only good for melting snow or boiling water, it does not simmer well. Now I have the Silent Cap (simmer cap) I will be using the stove a lot more.

bastante util funciona muy bien
