Raid Liquid Mosquito Repellent Smells Burnt When Plugged In

Hello, I purchased the Raid 45-night liquid mosquito repellent, but as soon as I plugged it in, I noticed a strong burnt smell. I’ve never encountered this issue before, and it’s concerning. I bought two of these, and now I can’t return them. This is frustrating, and I expect Raid to address this problem immediately. I’m disappointed that a trusted product has caused this issue, and I need assistance with either a refund or replacement. I look forward to your prompt response to resolve this matter.
