I got my lodestone 68 installer in L-0 a little over a week ago and took the stitches out a few days ago. The installation went well and removing the stitches wasn't too painful. I really want to start using the magnet, however I want to minimize scar tissue as much as possible. I will check the surface strength with the Zinc app later this week.
I can really recommend the Implant so far, especially in p-0
