This product consists of 3 parts. handle, joint and pin. No matter how large, ergonomic, well-designed or otherwise the handle is, its effectiveness and usefulness depend on the pin, which is the bridge between the handle and the hinge! This product arrived with an almost fancy pin! and I could see how fragile and weak the needle was! and that makes the whole product a useless and unreliable product. I tried and it failed! I do NOT recommend this product.
