At first only one light was not able to be controlled by the remote. But now 3 of them are not responding to the remote. Great idea if they worked properlyOne wasn't working properly went I received them but, loved the way they work with the remote and the colors and brightness was great to but, NO BATTERY LIFE!!!! Used them three times and the batteries went dead.Very bright little less thanks shipping was awesome!I ordered. this product to use in centerpiece decorations for an important event. Tested them when they arrived - 10 of the 12 pack worked. Needing only nine, I wasn't concerned. When it was time for the big reveal, only three lit. I concluded that it must be the fault of the remote that all didn't light. I ran out, purchached and replaced the battery, held my breath . . . nothing. Returning home, I began trouble shooting and discovered that the LEDs went on using the remote for a different product, but not using the remote that came with the set, even with a fresh battery. All signs seem to point to a poorly made remote that caused our centerpieces to not be lit. Very disappointed.PerfectThis pack of lights didnt come with a remote so they only can be used flashing multicolored which is not what I bought them for so its been a waste of money. If you can send me a remote then I can put these to use or allow me to exchange or return them since I didnt open this package up until after the return deadline.Remote did not work on orginal set I bought or replacement. False advertisement! Terrible item and a waste of time!I really liked these when I first got them then they stopped working after two days
