No bit of fancy alien tech is perfect, or so they tell me lol.I like the idea of the cloaking device only being fully effective when you're standing still. Small movements and slow movements won't affect if much, but a sudden move or a high-profile action like running or walking too quickly will compromise the effect, you won't be clearly visible, but perhaps a silvery outline could reveal your presence, or a shimmer like when air gets really hot.The subject of hiding smell and heat is debatable, but it certainly wouldn't mask sound.As for the shield only being effective against projectile weapons, it's a good idea. It would serve practical uses such as the wearer being able to eat and drink etc. while it leaves vulnerability to melee weapons which gives us an advantage as well as a shared weakness. And Groth, it was the personal shield that Dr. Rodney McKay found in Stargate Atlantis, it offered full body protection from projectiles and blunt force, as well as inertial dampeners that allowed him to fall from very high places without sustaining injury.As another thought, perhaps the cloaking shields are only issued to spies, that would make sure they weren't widely available to every alien, because the soldiers would be much more robust and probably have a different kind of armor, though still using a similar personal shield.
