I tried in-a-jet at another place, but it seemed like they did it too roughly. They said that just 15 minutes would be enough, but I felt like it wasn't enough... I only looked for places that could give it enough time. I went to a consultation and asked about it, but it was the only one. D&A confidently told me that it would take about 30 to 35 minutes, and I wasn't sure, but when I looked in the waiting room, they said it was the original Mermaid Jet, so I decided to choose more. And I got the real in-mode treatment in that much time, and it felt like the air jet treatment was done very meticulously! Overall, I was very satisfied and I am satisfied with what I received!
