.Starting Step:

(3)Turn on the power switch then rotate the flywheel clockwise quickly to start the engine on its right.
.Note:

(1)You need to add some water to the water tank after the engine works, for the water will enter the cylinder to fill the space after work and the water path in the cylinder will return to the water tank through the pipe.

Nice product
Color: 2-Speed Rechargeable Set with Charging Base
Edit: Customer service actually did offer to replace it. Received the new set and it works fine. Nice set. Only gripe is I think that the motor could be a little stronger. Sounds like it’s struggling at times. Received a defective item reached out to customer support for Circle joy and they’re basically saying that it’s user error and not a defect in their product, even though I explained to them that the other one works fine. When adjusting the coarseness on one of the grinders, the grinder ends up loosening up, which ends up with you spilling the pepper corns everywhere. It’s a nice set if it worked right but for $40 I expect her device to be a little more polished.

great for my bad hands, hygenic, easy to use.
Color: 2-Speed Rechargeable Set with Charging Base
so far so good. I cook a couple times a day. I also have bad RA in my joints. this product has really helped already. from the clean size adjustment to the ease of charging. Like i have owned it for years is how easy this product has entered my kitchen routine. strong product and hygenic because you adjust the grind from twisting the body, not messing inside the grinder.
