The smells are different depending on the device. Devices producing lots of vapour will give off a smell, while less vapour has less of a smell. The smell each juice gives off is similar to the taste and dissipates really quickly. The flavours in my devices are currently "honeydew melon" and "tobacco+caramel" which has a caramel-ly smell. As long as someone isn't blowing the vapour directly in your face you'll either barely notice, or it'll be like walking by someone that's wearing perfume or aftershave.
