My experience with the Ozonics HR500 has been a mix of positives and drawbacks. On the upside, its ozone technology shows promise in reducing scent, though not consistently. The unit is compact, mounts easily, and operates quietly. However, I found the controls a bit complicated to master, and the scent reduction results were not as dramatic as expected, considering the investment. Additionally, there were minor issues with the battery compartment latch. While the HR500 has potential, it falls short of my expectations.
