No Stars!! Very cheap and not worth the money. Actually if I got them for free I wouldn’t use them because the plug adapter they have installed is cheap and the safety of  plugging it into an outlet is questionable. 
It got very very warm within a minute or two and  nit one of the functions worked properly. Each setting began in a mode then quickly started flashing uncontrollably and the cheap adapter got very very warm
I tried both sets thinking maybe one of them was bad.  They both had the exact same defects and are cheap. Even the way they were packaged was shady. Crammed into a small box without being separated and no plastic bag or wrap
I have several sets of lights paying less for them and no issues.
