Hi There,
Thank you for reaching out. I apologize that you were not satisfied with your unit. I am wondering if the lights flickering had to do with which type of batteries you were utilizing. We recommend using Duracell or Energizer with all of our units. If it were not a battery issue then we can certainly help troubleshoot or send replacements. Please give our customer service line a ring so we can alleviate the issue for you, 877-298-9082. I look forward to hearing from you!
Best,
Aliece
