Other drawbacks include only a single period of "down time" per day. There is also an inability to totally block applications; the closest analogue is to set a maximum of one minute for the website or application.
Also, besides the resets (and by reset I mean not just time restrictions but content restrictions too), my kid can just bypass it by entering his AppleID password.
I use them myself to limit some websites that waste my time
It is way too easy to click on 1 more minute, or 15 mins or ignore for the day
The only way to really block sites is to add them as adult websites and turn on parental controls
But can’t do that with apps
You just give them the doohickey and ask for it back later. (Cloning the NFC tag is a much harder job that remembering a PIN.)

this is what I need
Heck, in many jurisdiction the device is owned by the parents anyway, not the kid.
