Well it takes time to get larger swelling, especially if you start out small. I think you should keep up and if you have time try twice a day. GIve it at least half a year, but preferably more and yes that is also the truth,sometimes the difference does not show on the tape, but more on the pictures, especially side pictures.
GIve it a real try, invest more time. But also to be honest, it does not work for everyone the same, some people react better than the other, if you would for example get only tiny swelling even after a year, it probably does not work that well for you, that doesn't mean that you cannot get any results at all, but no big improvement. I am not an expert, but I think suction works for people who get good swelling, without decent swelling it is unlikely to get bigger results. But as I already said, bigger swelling appears after some time, if you are small it takes longer to get more swelling. SO keep going to be sure you tried!
