Gailwrote a review of Optimus Fuel Bottle on August 7, 2015
Familiarity: I've put it through the wringer
The bottle itself is well made and strong. I have 2, .6 L, that are older and haven't had any issues. They even went through a 300 foot fall and though a bit dented, are still perfect. I bought 2, .3 L, a few days ago and while the bottle is just as good, the cap isn't. I'm not happy with Backcountry and this is why. I saw lots of reviews on here about the cap. I called in advance and asked about the cap. I wanted the old one that you see in the picture. They assured me that it was the same. When I received it, it was the heavy (very heavy) childproof caps. I called and spoke with them and that time they told me it was all they have. I asked why they haven't changed their picture. They said it's because Optimus hasn't sent them a new picture. Bull-cocky! They can capture a picture from off the Optimus website. I called Optimus this morning and they are sending me, free, 2 new (old style) caps for free. She told me the government made them change about 8 years ago and everything they send out is with the childproof caps. Why can't Backcountry change a picture in 8 years? I guess all fuel bottle now have to be childproof. I guess we have lots of toddlers out there on the trail! At home, such things should be put out of reach of children and it's the parent's responsibility! Since all companie's fuel bottle must have this cap now, then I'd give this a 5, but for the problems with the cap that is being sent out, it's only a 3. The cap itself is heavy, 34 grams or 1-1/4 oz. The bottle alone is 84 grams or 2-5/8 oz. The cap weighs nearly half of the entire unit!
