Noise Cancelling Ear Plugs for Sleeping Designed by CRIOXEN- High Fidelity Silicone Earplugs Musicians' Hearing Protection with Sound Reduction at Concerts

This machine replaces an identical unit that finally died after five years of daily use, which was a lot better than we had expected from something so inexpensive. Takes up very little counter space. The old mixing containers fit the new mixer base and not one of them has ever leaked. Very well designed. I sure hope that they never change it. Works perfectly. A real bargain!
