Size: Do you want something more discreet or is performance the most important issue? Are you looking for something that's easy to travel with? Then a discreet vibe is your best bet. Not only are these small and cordless, but most look fairly innocent, so accidental exposure won't make for embarrassing moments. Do you want something tiny that packs a big punch? Look into vibrating bullets and micro-bullets. Not only do these transmit vibrations extremely well, but many have pulsatronic controllers to stave off numbness. Is comfort most important to you? Definitely think about wearable stimulators; all come in a variety of sizes and levels of discreetness.
