Electric Fan

1) Something you use to cool yourself on a hot summer day. It provides a temporary relief of coolness, only to be fooled when the fan isn't aimed at you anymore and you instantly feel hot and sweaty again. You'd only wanna use an electric fan if that was your only choice, otherwise an AC is so much more better.

2) A synonym for something that only provides temporary or artificial satisfaction.

1) Moving into my new condo without AC was a nightmare. I had to make do with that small electric table fan.

2) TV series are like electric fans. It might give you temporary joy, but once the series is over you feel completely empty.
