Cell Lock Box - Timer Locked Box for Self-Discipline, Portable Time Phone Safe Lock for iPhone and Android, Lockbox to Reduce Screen Time (Blue)

I have ADHD-PI and find studying difficult as it is, but with my phone nearby it renders many of my study sessions unproductive. It's pricey but it works extremely well, plus it fits my iPhone 13 Pro Max WITH its case (a hard, clear one). It's easy to set up and it comes with instructions. It's been extremely effective and I can't complain at all. Battery seems to last a long time too. Just press the side 'open' button twice to open it, as it doesn't tend to open on one press.

The bottom that increases the minutes doesn't work properly also there are scratches on the case. Obviously, It is returned product and not new I regret that I buy it also I hate the process of return
