Have you used MobiiSpy software?

Hello everyone :

I’m looking for a good spy software for my son’s samsung galaxy s6. I’m not startying this thread to discuss whether parents should or shouldn’t spy on their kids phones.

I’m wondering if anyone of you guys can give any advice in this regard, please! I’m looking for efficient software that work well not something cann’t work longer than couple of days. I, also prefer something that can capture screenshots of the phone.

I came across “MobiiSpy” and I’d appreciate it if you can give any recommendations about this software or any other ones.
