Answer:
Ideas:
Instant Weight loss pills, Slogan: "Gain a little, Lose a lot!"
Kitchen appliance that washes counters (like a roomba, but for tables), I don't have any slogan ideas for this one
Self defense pen taser "It's sleek, chic, and shocking! ;D"
AR glasses (augmented reality, like VR but mixed with real life, like pokemon go) Slogan: "Gaming just hit a whole new level of Real"
I've got nothing else, honestly I think the pen one is the most simple
