Finally fixed my crooked outlets that bugged me for years. One minute install – drop the shim, tighten the screw, plate flushes right up. Metal feels premium, way better than flimsy paper.

As a DIY guy, this is my new favorite tool. Stackable design is flexible – two pieces filled a deep gap. Plenty in the pack to do my whole house.

Old house problem – recessed boxes everywhere. Used plastic before but they warped. These metal shims don't budge. Install once, forget forever. Solid investment.
