Pro IVs - 4 Colors

Don’t buy this!!! Unless, of course, you want something that will work for a month then stop… and you have disposable income.

Bought two of these here and both stopped working after about a month. Called the manufacturer, who was going to charge a fee and shipping both ways to repair. That amount was more than I originally paid for the device.

What is the frequency range of this unit?

I don’t see that info on the product page but here’s their contact info to get more information.
