Digi 1stT-5020 Fitness Interval Timer, Multi-Functional Training Timer with Pacer Black

This works nice for two activity HIIT, but also for splitting large runs into easy pieces. I will create 2 reps of 7:30/7:30 activities for a 30 minute run. This way, I receive a buzz on my hip at 1/4, 1/2, 3/4, and completion at the 30 minute mark, without looking at a watch.

Could be made easier to figure out how to set it, but I figured it out.Other than that, once you do figure it out (it's easier than Rubik's Cube, but harder than Tic Tac Tow), it is a very helpful and convenient and appreciated device.

If this product had clear instructions I’d give it 5 stars. It doesn’t. The instructions seem to be written by an engineer and then translated into English from another language. They are generous in quantity, but not in clarity. There have been remarks in other reviews that it is difficult to program at first. It’s really not so bad. I suspect they were simply befuddled by the instructions. The buttons are labeled well, and the display is easier to understand. And, unlike its nearest competitor, it actually stays on your belt.

i bought this because it said you could turn auto off. i assumed that meant it wouldnt automatically start the timer after each set. no, it just takes away the second timer. pointless.

This device was very easy to use, and all of its functions worked perfectly. I would highly recommend this product! I have been using this almost every day since I received it, it is part of my daily workout routine now.
