Outstanding customer service absolutely wonderful, works great It gave a great message I am pleased so far. The massager balls nodules are very intense on the back. Came in 2 large boxes that were relatively heavy. Just remember the massage balls nodules are stationary, you get the bottom of your feet to your neck, shoulders, upper back, middle back, lower back. Even your Bottom of your tush gets a great massage. Some of us have shorter torsos so others may have longer torsos this will affect where your neck is positioned in the chair. If you're shorter you can sit on a chair cushion to hit that spot-on area for a deep massage. Just lean into it, massage ball nodules That's what I do. Enjoy.
