IMAK Elbow PM

I had been searching for a few months for this nighttime elbow sleeve to help keep my right arm straight while sleeping & minimize effects of cubital tunnel syndrome. I was pleased with the listed price so I ordered it. It arrived very quickly & I have been using it mostly at night as intended. No complaints about this supplier; they handled everything to my satisfaction. As far as the product itself, I don't find it is stiff enough to prevent my elbow from bending with the plastic splint in the top-of-arm position as the manufacturer instructs. I find if I rotate the sleeve so the splint is positioned over the inner bend of my elbow instead it is more rigid & prevents too much bending.
