Terrible and unresponsive service!
I bought a 3 pack of the OdRXs. Within a week, they are significantly noisier than when I plugged them in and all 3 are hot to the touch, not just warm. I unplugged them and let customer service know I wanted to return them and I'm well within the 30 days of delivery. I have only received emails about reshipping the devices for units that aren't defective or keeping them with a very small discount. The company will not provide me with instructions to return their defective and probably dangerous product. I don't want a replacement since multiple units have issues. I didn't notice any difference in smells the week they were plugged in.
