Instruct: Classify Amazon reviews into positive or negative sentiment
Query: worth it

I had reservations about this device because it appeared so simple for treating a complex issue, but I have found it to be very helpful. If you need cervical traction, this is an economical choice that works. It does put slight pressure on the TMJ area, but I found it worked OK. I bought the unit after reading the amazon reviews. I usually don't write reviews, but I felt compelled to write this one to help anyone out there.
