Manual is for a different device
Operates OK. Instructions are badly translated. Instructions are for a different unit. Setup requires items that aren't included, like filter paper.

Not a long lasting product
Used a few dozen times and now the connection for the on/off switch is broken... It won't stay on unless I hold the button down or I tap it 100x and hold my tongue right.
