First I want to say, I love Viridesco products that use the plastic dispenser shown in the screenshot. The dispenser normally allows for extremely accurate dosages. I have a low tolerance so accurate dossing is crucial for me. I Just ordered this product on Sale and I believe it may have been sitting for quite a while before being sold as I am running into numerous issues that never happened before: I have easily bought over 30 Viridesco concentrates that use this plastic dispenser and have had very consistent wonderful results. Unfortunately, I am having a number of issues this time around: 1. The concentrate comes out extremely slowly or sometimes not at all when the dispenser is turned from one notch to the next 2. When the concentrate does come out, it is extremely dry and I have to use a paperclip to get it off. This only happened to me one time in the past and that was for a product that I had used very sparingly. That is why I am guessing the product I received was sitting on a shelf for a long time. 3. Once you are finished using the dispenser, you have to turn the dispenser in a counter clockwise direction to release the pressure. This has always worked in the past with my previous purchases. With this one however, the concentrate will continue to come out even after the pressure was released. It does eventually stop though The issues above make it impossible to get an accurate dose. It is hard to be too annoyed as I got this on sale. I guess I was just unlucky this time around as I have bought many sale items in the past. I may avoid Sale items in the future though as accurate dosing is more important to me than saving a few dollars.
