Review on Sae Arc Lumbar Stretcher Blue by Melissa Stout

My ex has one. I tried it at her house and liked it on my L4 convex disc. So I bought one and used it for 5-10 minutes every day for a week. Maybe it's too early to say for sure, but I think I have less sciatic pain in my left leg than I used to and it's less intense. I plan to keep using it no matter what. It's just fine on my back.
