Raid Liquid Refills Smell Burnt After Use – Immediate Product Inspection Needed

I purchased two Raid liquid refills, and within minutes of plugging them in, the room was filled with a strong burnt smell. I had to open the door and windows to ventilate the room. These products definitely need to be inspected. I still have both of them and am willing to provide them to the company if they are interested in investigating. I expect a prompt response and solution.
