iPod touch 7th gen, I own one, the apple parental controls are amazing, as long as you link to an account to apple id account is your own (as if u get the incorrect password 10 times it gives you the option to reset password through Apple ID).
I use the free version of the gentch filter which is gr8 besides it blocked random sites, and it doesn’t allow me to play individual songs on Spotify!
It is basically a phone without the ability to call or text ( there is iMessage), you need to connect to WiFi to use any internet.
