The Flexbeam is helpful for my lower back and also for gut issues. I use it everyday. You could improve the device by giving the user a choice of 10 or 20 or 30 minutes instead of just 10.Also the battery should be improved. I need to recharge it after every 6 of my 10 minute sessions. For me that means I have to recharge it at least once a day. It seems that it should last at least 5x that long.Also the price is quite expensive in my opinion compared with other red lite products on the market.
