MOLLE Bottle Opener is rated 4.2 out of 5 by 409 .

Rated 5 out of 5 by APas from Always Within Reach Convenient to have on the Hopper M30 as you can never have enough of these around. This one is always connected to the source. Be mindful of the angle that the opener is at when using as you may accidentally be pouring out the good stuff.

Rated 1 out of 5 by Pirate66 from Disappointed I should have been suspect as to why this product was to affordable! It does not mount well to the outside of my Yeti (keeps sliding loose) and since I am using it on the medium-sized Hopper, the angle is difficult to manage when opening a bottle. Buy the $50 Sidekick and keep your own bottle opener inside.

Rated 5 out of 5 by Mr Bean from Great on the go Perfect for the cooler, always there. Never have to forget to grab one.

Rated 1 out of 5 by dalvarez14 from Lost after first use I purchased this item for my new hopper backpack. After watching the video and installing it, the opener fell off and was lost after first use.

Rated 1 out of 5 by DW410 from Will get lost It doesn't stay secure on the cooler. Slips off the panel where it is supposed to stay secure within minute. This WILL get lost

Rated 3 out of 5 by Colline from Doesn’t stay on Slides around a good bit and falls off if you brush up against it too hard. Machining some small carabiners into each end would easily fix the problem
