Hello, I have used many juice companies, and Raw Generation is by far the best. I don't cleanse, but I drink at least one green juice per day to stay healthy and as a part of a balanced diet. Having the ability to keep them frozen until I drink them keeps me assured that I am getting the maximum health benefits of pressed juice, while still enjoying the great fresh taste. I have a standing order for 18 green juices every two weeks, and I simply pull a couple out of the freezer every day, so there are always fresh, healthy, and delicious juices waiting for me. Sincerely, Tim
