Yibuy Black 4" 5" 6" Bass Drum Adjustable Port Hole Rings for Bass Drum Percussion

It was easy to use. I would recommend putting it on a piece of cardboard on a hard surface to make your cut. Everything worked as expected with no extra cutting to or clean up.

Blade is dull would not cut thru the drum head.

Package seemed as if someone had already returned this product. The cutter did not cut(Not sharp enough). It ruined my bass drum head. Poor quality!👎🏼

The blade is not nearly sharp enough. It was like cutting a T-bone steak with a dull butter knife. I cut a port hole in my Remo Powerstroke Felt tone Fiberskyn head. Yes, it's a thicker head so that was probably the issue. However, I've used these port hole cutters before and the blade was much sharper. I did the best I can but ended using another blade to finish the job

Do NOT get the cutting device it does not work. Some say it does and how to do it correctly etc I say BS. The blade just is not sharp enuf. Waste of money. The hole protecter is perfect. A must have.

Don't waste your money. I have used other name brand cutters with no issues, but this blade wouldn't cut the Aquarian reso head. All it did was make deep makers and the center pin would not stay put. I wound up having to cut it by hand and I had to cut it larger because of the damage from the cutting tool. The foam rings were decent.

This is very cheap and poor quality the cutting tool was dull aa could be and made a mess of the bass drum head . Tried to save a few bucks, big mistake. The old cliché. You get what u pay 4. In this case POOR QUALITY DEFINITELY NOT EVEN WORTH THE PRICE PAID !

Tires using it on my Tama bass drum head and it wouldn't cut. Just kept making a circle. Had to break out my knife.

Esta herramienta cumple su función 100% pero es difícil de manejar. Recomiendo desmontar el parche del bombo y apoyarlo sobre un trozo de cartón o alfombra y esta a su vez sobre el suelo o una superficie estable y sólida. La navaja no es muy filosa, tuve que presionar con todo el cuerpo, girar y repasar el corte varias veces para que quedara y hay que aplicar mucha presión. Recomiendo comenzar con una presión regular para ir marcando el surco y después presionar con fuerza varias veces para finalmente cortarlo. El resultado? Mejor y más seguro que con cualquier otro método. Si eres delgado o tienes alguna lesión que te impida aplicar suficiente fuerza. Pide ayuda a alguien mayor

Um es kurz zu machen, die Klinge schneidet weder durch Felle aus Kunststoff noch durch beschichtete. Sie schneidet nicht mal meinen Finger!!! Kauft euch das Original von Thomann und meidet diesen billigen China-Schrott
