This TFA stopwatch has been incredibly reliable for all my timing needs! The 1/100 second accuracy within the first 30 minutes is perfect for sports timing and science experiments. The display is clear and easy to read, showing seconds, minutes, and even the date. I love that it comes with a lanyard - makes it so easy to carry around my neck during coaching. The LR44 battery that comes included has lasted me months with regular use. The split time function is super useful for tracking intervals during workouts. At 65x21x79mm, it's the perfect size - not too big but large enough to handle comfortably. The buttons have a nice click to them without being too stiff. I've used it for everything from timing my kids' swimming laps to baking in the kitchen to tracking presentation times at work. The hourly chime is a nice feature I didn't know I needed! Build quality feels solid - it's survived being dropped a couple times without any issues. For the price, it's way more accurate and feature-packed than I expected. Much better than using my phone as a stopwatch since it's dedicated to just timing functions. If you need a reliable, simple-to-use timer for sports, cooking, or any timing task, this little stopwatch delivers big time. Definitely recommend for coaches, teachers, or anyone who needs precise timing!
