Query: really not as good as it seems

The spandex-like lining is really thin and offers no stability support. The only support really comes from the metal brace skeletal structure. McDavid's similar braces provide better support because the support comes from both the metal bracing and the spandex-like material. With this Mueller knee brace, the spandex material does not hold the knee stable enough, it is tight but all it feels like is a tight women's stocking with metal braces...only good if you are looking for minimal support...i wish i stuck with McDavid.
