If he hasn't made his decision yet, then I want to put my vote in for a bottle with a window for measuring. Or just a clear bottle with marks on the side.
I'm sure there are a lot of things Frank has to look at when doing this. The good thing is he is listening to his customers and at least exploring new areas.
Not to complain but I hope he uses one with a little more substance. I bought three bottles and one had a crimp in the bottom. I really don't care about what it looks like on the outside, I bought it for whats inside, but I put it on my oil shelf only to find several days later that it was leaking. I don't know how much was gone out of it but it was a mess to clean up. A little stronger bottle with a clear window would be dandy.
Any time you have a indentation on the bottle to me it means the carrier caused it. All bottles are checked as good as possible at point of manufacturing & point of shipment to you. It is just the nature of shipping. Our goal is to get our customers ther Auto-Rx in good shape. Think we do that majority of times.
