This review is long overdue. I've been going to Kickin' It for several months now, but I keep forgetting to write my review. The first time that my wife and I went in, we were just looking for new juice flavors, which we found. While we were there, Mario spent a lot of time with us helping us to find flavors that we liked and he even let me try his setup, as I had been thinking about upgrading. I was sold. He is always super helpful, definitely knows what he is doing and can fix virtually anything. When I stepped up to an RDA, he took the time to teach me about building and safety, and was always happy to answer any questions that I have. If you've got questions, this is the place to go. Great shop!
