INITIAL REPORT
April 22, 2007

Primus Micron Ti stove, folded PRODUCT INFORMATION & SPECIFICATIONS

Manufacturer: Primus
Year of Manufacture: 2007
Manufacturer's Website: http://www.primus.se
MSRP: Not Available
Listed Weight: 2.5 oz (69 g)
Measured Weight: 2.4 oz (68 g)
Measured Weight in mini-stuff sack: 2.7 oz (77 g)

INITIAL IMPRESSIONS

The stove is packaged in a protective cardboard show box with the pot supports folded into their stowed configuration. The mini-stuff sack is below the floor in the box. Description of the stove on the box is listed in English, French, and German. Specifications on the box list the stove as producing 2200 W (7500 BTU/h). According to the box description, the stove will boil 2 cups (0.5 L) of water in 4 minutes and a small (100 g) LPGas cartridge will boil 6.9 quarts (6.5 L) of water or will burn for .6 to 1.2 hours.

A hang tag on the fuel valve states that the stove will produce 8000 BTU/h and warns that all combustibles should be at least "500 mm (20 in)" from the sides and from the top of the stove. There are also typical warnings that the stove is for outdoor use only and that it produces carbon monoxide.

The stove is built of aluminum castings and a number of stamped titanium alloy parts. It's construction is neat, clean, and there are no defects to be seen.

An instruction sheet is enclosed with the stove, written in English and 10 other languages. This instruction sheet includes safety information and instruction for handling, assembling, and operating the appliance. It covers changing the cartridge, maintenance, and obtaining spare parts.

TRYING IT OUT

Micron stove, unfoldedI discovered that the pot supports easily click into their extended (operational) configuration. In this position, they are quite secure and solid feeling. When folding the stove, I have found that it works best to fold the support which is aligned with the fuel valve first. In the attached photograph, this is the support which is to the left side of the stove. After that, the other two supports fold easily and neatly next to the fuel valve. If the order of the support folding is reversed, the legs do not fold compactly. 

After reading the instructions, I immediately screwed on a gas canister. The stove attaches solidly to the canister and the pot supports are firm and wide. The pot support surfaces are built with small serrations and my pot does not slide on them at all. This is good for maintaining a secure cooking surface.

After making sure that there was no hiss of escaping fuel where the stove mates with the canister, I put the canister on a firm surface for lighting. I cracked the valve open and lit the stove with a small lighter. The fuel valve is comfortable and easily adjusts the stove from a simmer to a full blast, and anywhere in between.

One of the features of the stove I learned about from a video on the Primus website is the small button of "catalyst" in the center of the burner. The point of this catalyst according to that video is to achieve a better burner flame in drafty conditions. My second experience with the stove was to use it outdoors without a windscreen. There was a very slight breeze and a half pot of water (pot size 3 cups (0.8 L) came to a boil fairly quickly with no attempt to shield the stove from air circulation.

After letting the stove cool, it was very easy to unscrew it from the canister. The pot supports fold into their compact configuration as described above. Remember the support above the adjusting valve is the first one to fold. I have found that it is easier in the long run to put the stove into the small stuff sack with the burner face last to go in. That way, there is less tendency for the pot supports to get caught up on the cloth of the sack when removing the stove the next time it is used.


SUMMARY

The Micron Ti 2.5 is a very light stove, the lightest canister stove I have had in my hands. It folds nicely and takes up very little room in my pack. It really puts out the heat, at a convenient turn of a knob. I am looking forward to testing the stove this spring and summer during my backpacking trips. 


FIELD REPORT
July 10, 2007

Micron stove in 3 cup pot FIELD LOCATIONS AND CONDITIONS

Field conditions experienced over the last two months included a three-day trip on the Appalachian Trail near Damascus. Temperatures ranged from 50-75 F (10-24 C). Altitude was from 1000-3500 ft (300-1100 m). The weather included lots of rain each day, but when I was cooking, it was not raining.  

PERFORMANCE IN THE FIELD

The stove is a joy to use. It fits easily, along with a small fuel canister, inside my 3 cup pot. There is room enough to add a lighter, a lightweight cooking towel, and a spoon inside the pot. This puts my entire cook kit inside the pot and protects the stove nicely. See the photo to the right. With the towel in the pot, there is no rattling of the cook kit in my pack when I walk the trail.

After opening the cook kit, starting to cook is a very fast process. I snap the pot supports in place and screw the stove on the canister. I easily have it lit within a minute of sitting down to cook. This is very appreciated at the end of a hard day of hiking.

My cooking is usually limited to boiling water, and this trip was no different. For breakfast I cooked oatmeal and tea. Suppers were noodle dishes. Using a pot cozy to finish cooking once the water was brought to a boil, fuel use was minimal. A half-full 100 g canister was plenty for the three days of cooking. About the time that I finished putting the pot in the cozy, the stove was cool enough to disassemble from the canister. Super simple!

In the "long green tunnel" that is the AT, there was not much wind, so I did not get to test out the wind resistant nature of the stove yet. I look forward to those tests during the long term report period with some Texas testing.

SUMMARY

This a a rugged, easy to use stove. It is light enough for even a confirmed ultralight hiker like myself to consider instead of alcohol stoves. It is compact and takes up less space than any other cook system I have used to date. Please consider coming back at the beginning of September for my long-term report on the Micron Ti.


LONG TERM REPORT
September 10, 2007

FIELD LOCATIONS AND CONDITIONS

The last couple months, I have taken two trips to different locations in Texas. I went on a three day, two night hiking trip to Big Bend National Park in late July. Temperatures ranged from daytime highs of about 85 F (30 C) to lows of about 57 F (14 C). The altitudes ranged from 5500 to 7800 ft (1700 to 2400 m). I had a long afternoon and night of rain and then a couple very nice sunny days. I also had a single overnight trip to Hill Country State Natural Area. The altitude for this trip was about 1000 ft (300 m) and the temperature was hot and humid: 80 to 95 F (27 to 35 C). 

PERFORMANCE IN THE FIELD

The stove continues to operate flawlessly in field conditions. In the humid, cloud-like conditions of the morning after the rain, my lighter would not light, but the stove lit easily with a ferro-ceramic striker. My cooking chores remained very simple, just water to boil for tea in the morning and more boiling water for noodle dishes in the evening. 

There was a bit of wind along the Northeast Rim of the Chisos Mountains one evening. Despite the drafty condition, the central area of the burner head kept the stove from blowing out. 

I remain very pleased with the light weight and the small packed size of the stove. It has been rock solid in all its mechanical components. It is a great match for the 3 cup pot I use routinely for cooking in the field. 

At Big Bend and at Hill Country State Natural Area, no wood fires are allowed. A stove is required for cooking, and this little stove makes cooking look easy. Add to that, its very light weight and it makes carrying my pack easy too. 

SUMMARY

The stove has made me think twice about continuing with alcohol stoves. It is just so easy to spark a fire and then turn it off when my water comes to a boil. The Micron stove has earned a continuing spot in my cool weather camping across the coming winter. I thank Primus and BackpackGearTest for allowing me to test this wonderful little stove.
