Did not fully read the description. It's 220 volts European plug not the plug for USA outlet. Haven't tried it out yet because of that

The media could not be loaded.  Tried to reproduce the water testing results at work only to find the device no longer turns on 👎🏻

I received a used item. It is clear in the pic that the label has been partially saturated with oil. I can't even use it as it doesn't have a standard plug. The metal posts are discolored from prior use. Very disappointed in this transaction. Returning for a refund

Worked as designed!

Complete waste of $10. The seller should make it very clear that this is only good if you have a 220V adapter or power supply. I don’t know for certain if it would work with an adapter because that is still 110V even with an adapter.From all the reviews I read, it won’t last very long after use.

JUNK JUNKItem not usable .threads on one post wrong size to big and on another not straight can not be assembled and selling EU 220v plug in USA will not fit without adapter for 220v . very poor to nonexistent Quality control . defective from manufacturer.PS AMAZON CHARGING FOR RETURN SHIPPING WITH PICK UP FOR DEAD ON ARRIVEL

After doing some research, it seems that this device does not prove that water is bad. It only proves the presence of minerals, which is not necessarily a bad thing.

It was intended for use In Germany, plug in cord would not work in the USA unless you had a plug in adapter.
