Review on 🔒 Pack of 3 S-Shape Airlocks with #6.5 Stoppers - Bubble Airlock Set by Kaveen Reyes

First caveat: Make sure you order the right size! While these are really great locks, they didn't fit my new 3 gallon bottles as far as I wanted them to be tight and secure. I ordered #6. It was entirely my fault. I love these "double bubble" airlocks. So you can see at a glance how active the fermentation is and if it's taking place, even if you can't see the bubbles (recognizable by the different water levels in the two airlock bubbles). Adding water is so easy and cleaning up is a breeze. For me, it was worth the extra pennies rather than the direct airlocks I used, making them good value for money.
