One more "Which implant should I get and other dumb questions"

Thats great news, this mean we are pretty much safe from any interferences damaging the implants.

Dam … I didnt even knew those things existed …

On the injection/location side of things.
Is it OK to have 2 implant (xEM & xM1) on the same P0 location?
(wish there were a NExT version with the xM1 instead of the xNT …)
Can you inject the 2 implant back to back in the same injection or you have to place it next to it/at a later date?
