Air WickScented Oil Warmer Plugin Air Freshener, White, 6ct

The weight of the bottle makes it "hang" from the outlet. This is not safe. How does this work properly?

What does the "Pack of 6" mean in this case? Are there 6 of the warmers or are there 6 refills that come with the one warmer?

Is this price for 1 count or 6 count ?
