This timer is great for any job that you purchase it for. It is durable and it has not given me any problems. I bought this little do hickie to put my grand daughter on a timer for potty training. It was a hit. She started to learn that when it got in the red it was almost time to go try to potty. She knew a treat would come once she pottied and brought me her ended timer. Not only that it helped with starting colors and helped with numbers. It made her want to learn more about it. It was great. I don't know if she loves it so much anymore. Now it is the the timeout timer. So I am not sure if she is so enthused by it anymore. She definitely no longer brings it to me. Laugh out loud!
