Amazing easy to use and works really well. Love the fact that the unit heats the water and uses ultrasonic action to clean. I placed a razor that is very difficult to clean, after 15 minute the razor was mostly clean. Added another 20 minutes and it was perfectly clean, guessing 20 minutes wasn't needed. Only thing that caught me off guard was how loud this thing is, best to set it and leave the room. Other than the noise, loved the ease of use and results.
