I didn't expect a simple lock box to actually change my habits, but this one genuinely helped more than I thought it would. The timer feature is the real game-changer—it forces you to commit to being off your phone, which is exactly what I needed for work sessions and even winding down before bed.
The build quality is solid. It feels sturdy, not flimsy, and the metal design gives it a bit more durability than the plastic ones I've tried before. My phone (iPhone) fits comfortably inside with room to spare, and I like that it still allows some airflow so the device doesn't overheat.
Using it is straightforward: set the timer, lock it, and you're done. No complicated setup. Once it's locked, there's no cheating, which is both frustrating and kind of the point. It really forces discipline in a way apps just can't.
That said, it's not perfect. The timer mechanism can feel a little rigid—if your plans change suddenly, you're basically stuck waiting it out. Also, it's not the most compact thing to carry around, so it's better suited for home or office use rather than on the go.
Overall, I'd give it 4 stars. If you're serious about cutting down screen time or need help focusing, this is a surprisingly effective tool. It's simple, a bit strict, but it works.
