Aukey 500ml Oil Diffuser, $20 with code AUKEYBE8 | 200ml, $18 with code AUKEYBE6 | 100ml, $16 with code AUKEYBE7

Aukey’s hefty 500ml oil diffuser can last up to 16 hours without refilling, and can also works as a color changing night light to boot. That’s not a bad package for $30.

While I probably wouldn’t recommend them for just a few bucks less, these smaller models are also on sale, though they obviously won’t run for as long with refilling.

Don’t forget to pick up some oils!
