How does it hold up in heat of the summer in FL?

Thank you for your question Huey, We've sold this unit across the country for over 10 years in Lowe's with very minimal issues. For Florida the biggest concern is the rain and humidity. So long as the device is used properly and placed vertically and not laid flat on a hard surface there are no concerns. It has been tested in a wet humid environment and the tester laid it flat and there were issues. The proper test is the item should never be tilted at more than a 45 degree angle. Within the proper parameters it passed all moisture tests
