NO Long term reliability
I have battled Sciatica for quite some time. I have tried many things with no luck. This belt did provide some much needed relief. The reason for the 3 Star rating is reliability. I have only had this for about 6 weeks and over a third of the lights don't light up anymore. The battery life is also not good at all. I can barely get in 2 30 minute sessions back to back. I use it on my hip where my Sciatica is worse and then on my lower back. Sometimes I don't get through both before the battery is done. I emailed the company and they said there was NO replacement for the battery.
Rating: 3 stars
