I’ve had my Titans in the backs of my hands for a little over two weeks now, and thought I’d give my impressions with them in case anyone else wants to go this route.
First, the left one is perfectly, and I mean perfectly placed. It sets between the metacarpals, and nestles down between them so that you’d have to know it was there to even find it (without a magnet or steel).
The right one got installed a little further towards the wrist. This was kinda my fault, as I had been messing with the cat about a week before the install, and cat scratches take a long time to heal. Pineapple didn’t want (understandably) to cut through an area that was still inflamed and possibly drag the infection deeper. So he started from a point a little farther back. End result it sits just barely on top of the metacarpals, and if I make a fist, it creates a very slight bump. I’m hoping that it works it’s way forward a bit, we’ll see.
I’ve been waiting and hoping to pick up some sensing ability, but nothing yet. Today I tried waving a wrench over it, and I could feel a little something if I got very close. It kinda felt like it was tickling the hair on the back of my hand. Then I realized that was exactly what was going on. Still no sensing. 
They both have a decent amount of pull. Just for kicks, I put a 1/4 washer on each one today, and have had them there for a couple hours now. I think they might come off if I was swing a hammer hard or something.
I guess I’d rate the whole thing as an excellent install, in a poor location. I’d definitely consider putting an X series in one of the spots if I ever had the desire for another.
Still debating if I might have these yanked and moved somewhere else, or if I might just buy a couple more and have them installed giving me a 4 pack of Titan awesomeness.
We have some fairly powerful electromagnets at work, I might see if I can pick up a tingle near those sometime soon.
