We were attracted to the 10 year life and bought a two pack from Bunnings.
A few months after installing, it went off at 2am. We could only hush it for 60 seconds and then it started up again. We couldn't open it to remove the battery - because it's made to be closed. In a now funny story, husband and son had to get tools and pry it open and cut wires as if they were defusing a bomb. It was the only way to stop it and, of course, completely ruined it. We had lost the receipt but wanted Bunnings to know about it so my husband emailed them to ask them to tell the manufacturer. He received no response from Bunnings. We will dump the other one - a crying shame.
No, this product has too many drawbacks.
