Darkglass Harmonic Booster 2.0 Clean PreampThe Harmonic Booster, Darkglass Electronics' first circuit, was meant as a gain stage for distortion pedals but evolved into a powerful clean pre amp. It allows bass players to boost volume and shape their sound without adding distortion. Each volume and EQ control provides a 20dB clean boost or cut, along with a parametric mid control. The unique Character control flatlines the signal when off but adds low end beef and high end sparkle when turned

Great can opener
All you have to do is put this on top of your can and push the button. So easy.

Works great on many different size cans
Works great on various size cans. It is a little larger that other openers, but seems very sturdy. It is a little loud and slow, but not a large concern. Very happy with it.

Stopped working after 3 months
It stopped working after 3 months.
The motor still runs the gear still turns. But it does not engage the can to cut.
I bought it for a post operative situation and I am glad that it worked when for the length of time it did but it's disappointing that I now have to throw this item away.

Meh.
Worked great the first couple of times it was used. But then it stopped cutting into the cans and does not open them. It causes the metal to fray off in small pieces which resulted in getting a piece of metal stuck in my finger for weeks so I don't recommend. It's also very loud.
