this is my fourth or fifth speaker now and I hadn't noticed on the newest TOUGH version that the metal outside 'loop holes' where you can strap the speaker to anything with a cam strap is now gone. This makes it difficult/risky to secure to places. I'm a little disappointed with that change and may have gone with a different brand in favor of being more securable. So we'll see how it handles being taken out into the wild.
Really loved the product in the past and had recommend this a bunch to others but this small change could be an issue.
