Jiawu Cube Timer, Sensor Flip Timer Kitchen Timer, Digital Clock Timer Backlit Display, Mute & Adjustable Sound Clock, 5, 15, 25, 45 Minute Presets, Timer for ADHD Kids & Adults (White)

The function to set a timer by pressing multiple buttons simultaneously is not included, nor does it have a vibration feature. Additionally, there was a slight issue with the battery contact, which was resolved by manually adjusting the metal contacts of the power supply section. Other basic functions generally work comfortably.There are some clear discrepancies in the guide, but considering the price, I rate it three stars.
