Review on WALI Security Flashing Warning SD 4 by Drew Gengler

I wanted to put some of these in my house. After reading the reviews I decided to put mine in without the batteries as the red light was not needed and it made installation easier. I attached double rods to the back and glued them to the porch ceiling and back awning. They've been running for a few months now with no problems. One thing I did because I couldn't get to the porch ceiling without a taller ladder was get a butt in the bathroom. I attached the self-adhesive piece to the back of the dome and then removed the top of the self-adhesive piece. I placed the dome face down in the flask bowl and used the flask handle to reach the ceiling. I pressed the plunger and held it down for about a minute to attach the dome to the ceiling. Worked great!
