Salt

I know you have zero control over this Jeff, and I'm not sure if any others have ever complained regarding the 50 mL bottles (for Green Gain, Phyton Git, ECA, and Green Bacter).

The holes in the droppers are too small! What ends up happening is they eventually get clogged. Then when you're trying to count drops, it gets stuck... so you squeeze harder, then you get a big squirt, wasting a bunch of product!

I thought the dropper caps were sealed on, but I discovered they aren't... I was able to pull it off with a regular pair of pliers then use an eyedropper.

But for what it's worth.. I sure wish ADA would make these bottles with bigger holes in the droppers so they don't clog!
