Review title: The best airlock I've tried
Product review: These are a very effective airlock. You can install it and then poor in the vodka,iodine water or whatever you want to use (don't use chlorine water) and away you go. The best part about these is that they are EASY to clean. The S shaped airlocks are too difficult to clean (re impossible). The only negative is that the S shaped airlocks are slightly easier to see the bubbling action coming through them. So bottom line for me is that if money is no object, you might consider the S shaped airlocks if you want to see the action better, but you need to throw out after each use in my opinion. And if like me, you replace airlock with a clean one about 5x with each batch, then you see the ridiculousness of S shaped airlocks. If you want to reuse the airlocks, then these are the way to go. I put only four stars because the bubbling action is a little harder to see.
