Flexnt instillation questions


I would like to purchase the flexnt but would like to get some more information first so if anyone can help me I would greatly appreciate it. Does the flexnt have to be installed within a certain period of time after purchase? because I don’t know how long it will take to find someone willing to implant it. Secondly would it be safe to install on the side of my dominant hand in the area between the pinky and wrist? lastly can anyone offer insight as to how day to day activities are affected if at all due to the flexnt?

thanks for your time.
