Product review (5 stars): Exactly was it should be.
Literally plug in and go.  Working very well in my Ozone machine.  DO follow the directions and have a fan blowing on this plate and your machine, to disperse the ozone and also keep the machine and plates cool.

The only weird thing, mine came with a packing slip addressed to someone else.  I'm assuming someone else got my packing slip.  This is a bit of a privacy concern but the device itself is fine,
