This system is amazing - great for two (2) to share on the trail - MSR WindBurner Duo System

I purchased the 1.8L System over the 1L system as this system allows for a remote fuel canister, larger pot and a lower center of gravity so tipping is less likely to occur. I have also purchased the compatible MSR WindBurner Accessory Sauce Pot - 2.5 Liters for larger group trips and campground cooking rather than backpacking. For backpacking MSR also makes a 1 Liter Windburner accessory pot as well as a coffee press if you're interested. I plan on predominately utilizing this stove with the 1.8 Liter pot for weekend backpacks for two. Sharing the stove weight between two people will reduce what the two of us need to carry.

Pros:
Wind resistant
Fast Boil
Easy storage
Relatively Lightweight - 625g (22oz.) including the 1.8 Liter Pot
Allows for a greater array of pot/pan attachments (including some that are Ceramic) than the WindBurner Personal Stove System

Cons
May not simmer as well as some other stoves - I am not 100% sure. I mainly have this system to boil water for coffee and dehydrated means.

Overall:
Happy with purchase. My intended use for this will be for 2-3 people backpacking, camping (3-7 nights), and car camping but not recommended for thru-hiking.
