Not a bash, and barely a negative, but something I noticed after a few weeks of receiving my two BIG RF SC flavors. All flavors were 1oz. bottles with caps that appear to have cones which should offer great seals. After a few weeks of setting up single flavor testers (shaking the concentrates before mixing) I noticed a few of the bottles would spray little dropletts when shaking, then a few more. Really cranked the lids down to no avail. Walt eluded to the fact that there had been some caps that were changed, so perhaps both my orders were the "happy" lids, but unsure. I also noticed that my flavor lab was MUCH more, ...... ummmm, ........... FLAVORFUL when walking in so I'm passing this onto the crew here, as my experience to you. I'm in the process of moving all my RF SC's into 30ml clear PET bottles, which will eliminate the FLAVORFUL-ness of my mixing lab, provide better sealing, and eliminate the dropplet ejection when shaking them up prior to mixing. The BEST part is, the original labels come off easy, and go right back on my new PET bottles.
Love the flavors, and even the very few that I wasn't blown away by, are far far away from a dud, so no complaints about the flavors at all, just have to tweek the storage a bit.
