For the money, it's amazing! I've had it installed for a month now and it works perfectly. It has withstood rain, wind, and relative heat, and it hasn't been damaged at all. The only thing that concerns me is that the plug of the cable coming from the panel doesn't fit all the way into the socket, and I don't know if it might cause issues over time.

Edit: 9 months later, it's flawless! They are building an apartment building next to me, resulting in the panel getting splattered with cement, yet it continues to work normally!
