Query: Heathco = Junk

I bought three different Heathco motion sensing lights and all three had problems. I bought them at three different stores thinking there might have been a bad batch or something... Each was defective in its own way. The "dim" mode never come on the first one. The second never turned off, it stayed full bright all night. The third one cycled on and off every ten seconds. I read the instructions, reset by turning off/on, reaimed lights...even emailed Heathco. Guess what? They never responded. POOR QUALITY AND POOR CUSTOMER SERVICE. A losing combination for sure!!!
