Failed in heavy rain
I bought one of these about two years ago. It failed about a week before the warranty was up. It was replaced without charge. This replacement one was fine up to about a month ago (about a month after the warranty was up). It started to go off incessantly until I had to turn it off which is inconvenient when you are expecting deliveries. I took it apart only to find it was full of water and rusting where the batteries are secured. I allowed it to dry and cleaned it up with an electrical contact cleaner. Put it back together and hung it out again. Again, full of water within a few days. I repeated this process once more. This time I tried to seal the edge with hot glue hoping it would protect the interior but easily removed if there was another problem. It went off in the middle of the night. I've since taken it down altogether. There was not much water in it this time but it's still unpredictable and unreliable.
The company responded to my initial review on Home Depot Canada website saying they would contact me to resolve the situation and that I should email them. I emailed them 3 times but they never responded. I believe their response to my complaint on a public website was to make it appear as though they would rectify the situation but they ignored every email.
It's poor quality and their customer service stinks!
