Not to hijack the thread, but I also have install questions regarding the flexNT.
Would it be advisable to have it installed on the second segment of my middle finger? With a pair of calipers, it seems like it would fit between the knuckles (25mm), but there’s not much wiggle room. I ask because I wear rings on my right hand that would interfere with the tag should it be installed where it’s shown in the pictures.
