Piano Tuning Kit Professional Wrench Hammer Rubber Mutes Set Including 9 pcs Tuning Tools for Piano Tuning with Tuner

I am very satisfied with the quality and effectiveness of these tools. Using them to tune a 105 yr old piano that has not been adjusted for 50 years.

Creo que sirve para hacer ajustes para afinar, pero si eres un afinador profesional definitivamente no lo comprarías. Porque la llave es muy pequeña del mango, a veces se necesita un largo mas grande para algunos pianos.

Haven’t actually used this product yet, but upon initial inspection, after the prompt receipt of this order, it has been determined to be of sufficient quality and endurance to complete the task at hand.

The product works fine, except that I'm a bit curious about the wooden handle, but I think it worth the price.

It worked fine for me, but a longer handle for leverage would have made the tuning easier. I would have paid more for a longer handle had I known. Also the felt was too thick to thread in my strings so didn't use it.
