Did not come with the 24v power supply as stated in the description. I have a different one in my bathroom but wanted to try this for the patio. Paid more for this since it said it came with the power supply but sadly it did not.

    Garbage!
  

*by B***I on Reviewed in the United States on July 7, 2019*

Everything fell apart.  Had to use parts off a 2nd one and at the end realized it’s still doesn’t work. Installed a Pyle and it was much cleaner. Still needs work
