T-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.

The instructions are great. I found them to be very straightforward. This device is perfect for timing up to two intervals. The frequency setting in Pace mode was a little tricky. If you are pacing steps, and you want the frequency/footfall of each step to be every second, set the frequency for 0060. That’s a pace of 60 [units/steps] per minute. Think of it like beats per minute on a metronome. Also check out the Leap device and the Taylor timer (not an interval timer, but dead-simple to use and has a flashing light if you want it.)

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.

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.

Though the instructions were followed to the letter, this product failed to operate properly. It is small and the size would work great for the gym, but if I cannot get it to track time correctly then it is not a good product. I do not recommend

I’ve never had a specific interval timer before. When I went to a 3-day boxing clinic the trainer’s interval timer was much larger. And so far, having read the instructions 3 times, I still am unable to set it. Once I get that working perhaps this thing will be functioning like crazy.

Love it. My back up to my other clock

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.
