Scott M:"I have bad knees and was worried about the vibration. But the shaking is super smooth, not jarring at all.this thing grips my tile floor and doesn't slide an inch, even when I'm really going for it. Feel totally safe."

Trustn C:"You can tell the difference right away compared to cheaper models. It's sturdy, the materials feel nice, and it operates really quietly. The gentle vibration is easy on my body. It's not one of those flimsy things that'll break in a month. "

Janet N:"I'm not a gym rat at all. This is perfect for me. No confusing settings. Just turn it on, maybe connect some music, and go. It's gentle enough for beginners but you still feel it working. "
