I got the unit installed around 3 days ago now and the bond was still very secure (2 week eta I'd say) and I have been going to gym without issues. I wasn't too keen on the tape on the hairline as it was making it too obvious.
I just reattached it at home with tape along the perimeter of the rear/sides and glue on the front hairline. The center is not bonded with anything but it doesn't feel worse in any way. I used scalp protector as a primer for both the tape and glue.
The hairline is almost invisible now. There is a patch in the hairline where the unit has reduced density (noticed this when the unit arrived so it's likely a quality control issue for Lord Hair) and if you're staring at it and the light hits it just right, you can see the shine of the poly base.
Experimenting with some stubble that I might graduate to a beard

And here is a photo of the bald spot, it's the most obvious spot, but again not noticeable unless the light hits it at the right angle

If I decide to keep rocking the exposed hairline I will try the injected poly system from Lord Hair next time.
I feel like I am getting pretty comfortable removing and rebonding units at this point. The next step for me is to learn how to cut a base against a template (I got my template from Transitions Hair).
