I found the graceful curve on the backside did not engage as solidly as more agressive angles on hexes such as the Black Diamond Wired hex set; especially on jagged cracks.

Still a great set for setting up TR for youth at work.

emack is right; however you climb, you need these.

Never leave home with out it. Double up on your small sizes.

A decent stove, but in my opinion is a less reliable, slower to boil, fuel guzzeling, albeit quieter companion to the Dragonfly.

If might be out on trial for more than a night or two, cook on uneven terrain, have to melt/purify water on your stove for drinking, or cant live with a breakdown in the field. Get the dragonfly. If not, feel free to use the whisperlight, but you probably don't need the international.

Reliable from the desert heat to the Arctic cold; in the wind, snow, and rain. Lights up after being dunked in water, melts snow and boils water like a flamethrower, less likely to remove eyebrows when under your vestibule. Forget about saving a few bucks and a few ounces and get the stove that fires up right the first time, every time.

The pump stroke is too short, requiring more work for less drinkable water. The handle does not pack down well and I've seen the break off in the field. The O-rings are prone to leaking. They are a pain to clean.

Do yourself a favor and get the sweetwater.

I picked up one of these before MSR bought the company out. Pumps faster and more reliably than any other micro filter I've used. What more do you want?
