Query: They Work Fine - No Surprises Here

Not a whole lot of say about a couple of lantern mantles. We love Coleman products, they work as they are supposed to, and they aren't really any surprises. The insta-clips mantles have a few seconds of learning-curve when attaching them to the lantern, but we figured it out after a few moments. Super bright, and easy to use.
