My dad has had one for probably 15 years, and uses his several days a week for 5 minute hangs. 10 years ago I tweaked my lower back and could barely move, so I went over and tried his...a few days and I was sold
. A coworker had serious upper back issues, but the table didn't help his situation, so I purchased his really nice one for 150 bucks and use it on occasion when I injure mine. Hurt mine a few months back wrestling with a large outboard lower unit in an awkward position...right between the shoulder blades....didn't use the IT...wasn't gonna help. So...it just depends...I love mine!
