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.

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.

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 !

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!👎🏼

Do NOT get the cutting device it does not work. Some say it does and how to do it correctly etcI 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.

Dullest blade ever. Not useable at all. Save your money and skip this one.
