When the device is plugged in, a blue ring of light will blink around the On/Off button. There are five different settings to choose from when using this device. To start it, you turn the dial to the desired speed and then press the button. In general, to get the best juicing yield softer produce should be juiced at lower settings while harder produce should be juiced at higher settings. We measured the noise level at 82 dB, which makes this the second quietest juicer in our lineup. This is surprising considering how efficiently it juices. It also has rubber non-slip feet and doesn't vibrate excessively when juicing.
This juicer is worth it's value. That said I note that since it is a sintrifical force juicer it seems to make much more frof then other slow grind type juicers and the remining pulp is still wet, so not all of the juice was removed ( or more could have been removed). I do like the eaz of break-Down and and reassemble and it is easy to clean. It is small enough for the counter or storage area. If you are starting out and looking to explore the world of juicing - start right here. Enjoy!!
