  • "I've owned this for several years now (from Kickstarter) and I have to say it's not worth the money. My only gripe with is happens to be it's biggest crux of it's engineering, and it's just not capable of cutting the materials it's advertising. The reason why it cannot handle them is because of it's poorly designed knife and a single set screw to hold it in place. With 40k vibrations per second the blade needs to be precisely fit inside it's holder and if it's not, then it vibrates itself inside it's little slot, diminishing the affect of the ultrasonic waves. Because of this I estimate it's only able to cut at 20% capacity."
