Quoted from another user's review:
Just fill with tap water to the level that fully submerges your glasses, turn it on, and your eyeglasses and sunglasses will be cleaned.
In about 5 minutes, even the parts you can't reach become clean.
It was also very convenient for cleaning inexpensive earrings and studs.
It uses AA batteries, so there's no need to plug and unplug cords.

Batteries are not included, so please provide your own.

Overall it is clean, but there are some minor scratches.
(See the last image)
It feels like a shallow scratch rather than a crack.
