Takes some getting used to, but secure

I've put it through the wringer

Got this when my decade old cap finally was too damaged to use anymore. Great, tight closure as normal for MSR caps, but this has the added benefit of keeping my kids from drinking white gas (generally a good idea). The opening mechanism seems slightly un-polished, and it's a bit hard to use, but it's very secure. If you don't have kids or some other reason to have a really secure cap, I'd recommend the normal twist on cap.

It works

I've put it through the wringer

It does what it needs to and it is still easy to get off. I never store my fuel bottles with fuel in them so the child proof cap isn't really needed. I am more of a fan of the traditional ones but you have to take what you can get.

a bit annoying

I've used it several times

This cap came with my bottle. it is a bit annoying to open at first but you get used to. Also I feel more safe with it on my bottle.

Must have for children

Otherwise, no need. But it is a nice sized cap that's plenty large enough to grab and twist.

It works very well if you have children, but I will agree with Evan and say that it is a pain and if you dont have children just go with a normal cap.

It's good if you want it, otherwise it's a pain in the butt. I have one of these on one of my bottles and a regular cap on the other. Anyone know where to buy the regular ones?

I'm glad MSR finally got this lid! Works great!

Me too. BTW I think you have a great name; when I write my book I would like to use it for the hero.
