Review on ⏰ 24 Hour Digital Timer with Countdown, Count-up and Clock Feature - Batteries Included (Black Table Timer) by April Irvin

Very poorly made - first timer I bought of this model was excellent - this new one didn't open to insert the battery. I also bought 2 smaller marathon timers which just stopped working within a year of light use. I finally managed to open the battery access slider with extreme force and prying from a screwdriver. Replacing the battery this way is too dangerous, you will cut your hand. I snapped off the tab that secures the slider in the closed position and used white tape to secure it. I have no interest in cutting my hand with a tool just to change the battery.
