Customer Reviews

Good things come in small packages
I'm pleasantly surprised at how small this interval timer actually is while at the same time having a large enough display to be easily read.

The beeping alarm is very loud. If you read some of the reviews of some sport watches (quite expensive ones) that have interval timers, most of them mention the alarm not being loud enough.

My favorite feature the Gymboss has though is the vibrating function. I run while listening to my MP3 so I set the alarm to vibrate instead of beep, and that is something you will never find in a sport watch that costs the $19.95 I paid for my Gymboss.

If you're shopping for an interval timer, this is definitely the one to get.

Nice little interval timer
Gymboss timer is an inexpensive little interval timer that works very well for the price. It's the size of a matchbox and it's easy to clip into the waistband or even collar of your shirt. The belt clip is very secure, so there is little danger of the timer slipping off you belt. It would have been a nice addition though if there were a strap that would allow you to fasten the timer on your upper arm or an exercise machine, for example. Another improvement would have been if the belt clip would rotate, so that the display screen would be facing you the right way, no matter how you carry the timer. And speaking of display, it could be bigger and/or have better contrast.

The timer is plastic, and although it can stand being dropped to the ground, it would probably not take when stepped on, for example. They also market as water resistant but I would not use it with water sports, although it's not affected by the moisture if carried next to skin under clothing.

The timer has two different alarm sounds, and an optional vibrating alarm you can use together with the audible alarm, or just by itself. However, I feel the vibrating alarm is not strong enough to be relied without the sound, at least when engaged in a vigorous activity like running. In addition of having two different alarms, you can choose between alarm length of one, five and ten seconds. The high alarm voice is loud enough to hear the alarm even in the middle of traffic, and the lower tone alarm is good when exercising in more quiet environment like in your own home.

The timer has the option of using two separate intervals of different lengths, like Tabata intervals or boxing rounds. You can program the timer to go through a set number of rounds and then sounding an end of exercise -alarm, just counting rounds until you decide to end the exercise, or just simple countdown with no separate rounds. The rounds can vary in length between 2 seconds and 99 minutes 59 seconds.

It's easy to program the timer, but it could be a little faster. For example, if all I want to change is the number of intervals I want to go through, I have to go through the whole programming cycle just to add or reduce the number of rounds. It's not a big issue, but it there was a switch to choose which variable I want to change (the length of an interval, the alarm sound options, etc.), it would make the programming easier. I like the fact that the start/stop button of the timer is located on different side of the timer than the programming buttons. That way, it's easy to locate the start button by feel when the timer is on your waistband. You can also pause the timer by pressing the start button three times in succession.

All in all, I am very pleased with Gymboss timer. In fact, I'm so pleased with it that I'm considering buying another one for the office.

A Boss That Works For You
For the money and the design, I think this product is a great value. It's easy to set and use, which I appreciate. It's great for runners, who are into running splits and for someone like me who wants to get more into interval training to burn fat.
