I hesitated for quite some time about the Vocal Trainer, mainly due to the cost. I kept watching the videos and reviews and finally decided to move forward, and I genuinely wish I had done so much sooner. The progress over the first few weeks has been truly incredible. I can see a difference in sustain and the ease of runs in both higher and lower octaves. I use this twice a day during my usual 10-minute vocal warm-ups (Jacobs Vocal Academy).
