Some functions are fine. If you are buying this for media functions like streaming video or audio, it doesnt work.nor screen shot photo. Cust svc claims the internet connection isn't good enough, but the target device was on line with every other app, messaging, videos, etc.. So there was plenty internet. Not sure what super duper internet strength is required, but it was not disclosed up front and it does not work!! If you want to track web pages and screen time, or location tracking it is fine but can get those functions from several free apps also. USE:DARKHACKHUB.com INSTEAD>>>
