I own quite a few jig head molds, with four of them being CNC machined. All four are from different manufacturers. This mold is superior in every aspect. The hooks are easily positioned. The mold has a solid hinge and closes perfectly. The cavities fill completely and without requiring a special technique. The heads separate easily and the sprue snaps away leaving a small blemish. This does not require filing or sanding as powder paint easily covers it. The heads weigh exactly 1/16 ounce. The engineering that went into making this mold is top notch. Knowledgeable folks. I wish I could start all over again. I would buy all my molds from these people.
