Wallflower Plug Ins

Hello, I’m fairly new to the Bath and Body Works community here on Reddit. I am also new to Wallflowers as of the most recent Disney collab. I was in store today, wishfully hoping I might find the Belle Wallflower, Belle sani pac holder, or the Castle Wallflower that BBW cancelled on me very last minute. Anyway, when I was in store looking at wallflower units, I was surprised when a worker informed me, that the units rarely last more than 6 months. She said with proper care including not having it plugged in 24/7, they may last a year. I wanted to know how true this is? What has your experience been using the Wallflowers plug ins? Has yours lasted more than 6 months? More than a year? I just ordered quite a few with the Disney Collab, and I’m debating on whether I want to keep them if the plug in units don’t last very long. Thank you!
