I originally made a negative review because it had died on me and was not charging at all (no red light, nothing). For whatever reason, some chargers work and some don't, even though it is the same USB type C charger. Also, it takes a very long time to fully charge from red light to green light. Like 8 hours long. Regardless, this is my absolute favorite timer. I use it more often for myself as an individual with ADHD to support with time blindness and for my toddler to help understand the concept of passing time. I used visual timers when I was a teacher as well. I couldn't recommend them enough. A friend bought one recently for a roommate with ADHD and they loved it! Honestly, in the end it's a timer and anyone can benefit from it.
