I bought this deactivator to use in my office. This diffuser has problems. Every time I take the top off the rubber seal comes loose and I have to struggle to put it back on. I want my transmission to run all the time and not be interrupted, but it turns itself off. I've already had to replace the wick, before that I'd only used it for a few days. In addition, the upper part ripped at the attachment point after the first use. Very disappointed!
