I did it alone in about an hour and I went slow. I think if you want an actual waist trainer CINCHER to "snatch you in" under clothes and want to "sleep-train" as well, you should get one of the conventional Yianna corsets which is what I have also ordered. I recommend these highly. Easiest Set up and more advanced software of any USB Mic I have ever used. Fits well, very comfortable, and great quality. Once I got the first plug linked, the rest were almost automatic. On that note, however, the azimuth, tangency and overhang were correct according to all my protractors. Pros: Light, comfortable, and responsive. I suggest just buying an actual decent set, it might cost more but theyll certainly last you alot longer. Si después de más de un año que llevan en el mercado estos auriculares no han solucionado este problema, dudo muchísimo que lo vayan a solucionar.
