I purchased these lights for my balcony. The lights themselves look great, but the plug prongs keep coming off. I’ve been able to rig them to fit in the plug (not the safest thing to do), but tonight, I was unable to get the prong back in. Now my balcony is dark and I have a string of $30 lights wasted. 

Overall, I’m very unhappy with this purchase. Bought them in April and only lasted a few months. A waste of money (for lights that aren’t so cheap).
