Works as intended. Once you learn the controls, it is easy to use! The vibrate function is great can be used alone or with the beep. I personally use this not for working out, but to remind me regularly all day to get up & move around / change positions (I have chronic pain that improves if I do). It also reminds me to stay focused on tasks I need to do. It's wearable, so I never lose it! Very useful!

I needed a timer to so some intervals during workouts. I have an app on my phone, but it wasn't convenient since I like to use that to pump music into my music server. So wanted a standalone timer that was easy to setup and carry around. This Gymboss is pretty easy to set up – in fact easier than the phone app I have. One minor gripe (I have several with the phone app!) is the awkward end of routine timer. You have to press the left-side button twice to stop the alert once the routine is finished. Nice additions are the rubberized finish on the timer and the clip on the back. The fact that it runs on a AAA battery makes it easy to get new batteries as well. All in all a great timer for performing intervals or pretty much any timing need.

If you do any sort of tabata or HIIT workouts, you need a gymboss, it will change your world. When I do HIIT workouts on a spin bike, I don't want to count in my head or have to keep looking at a clock on a wall or starting/stopping a timer. Enter gymboss! Set the interval times – exercise time and rest time – clip on to your waist and it will tell you exactly when to start and stop. You can set it to beep and/or vibrate at each switch from exercise to rest time and for how long it beeps/vibrates. If you're in a crowded gym or working out next to someone, I'd recommended turning off the sound, it will annoy people. Love this, lets you really dig into the workout and concentrate on giving full effort w/o having to think about keeping track of time. Very convenient – easy to throw in gym bag and very small and light, comes in cool colors. It's a little bit annoying to set all the times and settings you want, but I tend to use the same number for a couple weeks so it's fine.

I've only had this a couple of weeks but absolutely love this. I've nick named it "The Motivator" I've been walking, jogging and doing push -ups for about 5 years now. I'm 59 years old and am very routine oriented. I've read about interval training and have always wanted to do sprints and walk but have had some concern and hesitation. Although I do not have any knee problems I just didn't know if my body could handle it. Anyway a few weeks ago I decided to try it. So when at the park I had no time keeper but tried to count 15 seconds while sprinting and 1 minute rest and repeated. After this one lap of that I walked a few laps. I felt so good and invigorated. The next two day's when I went back to the park I did my usual 2 lap walk then did 2 laps of sprints and walk and a final lap of walking (3 mile total). This is fantastic but I know I needed a time keeper, so I looked here on Amazon and found this Gymboss Interval timer.
This timer comes with very good instructions to teach how to set it up and use. I absolutely love it. In the few weeks I've adjusted my sprint time from 12 to now 15 seconds keeping the one minute rest. I've also increased the amount of sprints I do in total. This timer actually is motivating me. I can't wait to get back to the park to do my exercise. It has helped to revitalize my workout routine. It's giving me goals to attain and makes my workout fun. It is very light in weight yet feels sturdy. It has a very strong clip with good grab. I clasp it onto my shorts and feel confident that it won't fall off. The audible beeping or vibrate modes (or both at the same time) work very well for the interval training. It is also a stopwatch which I use during my walking laps, and a clock. Great price for all the value it has brought to my workout. Wish I would've gotten this years ago. I highly recommend this timer to anyone looking to revitalize their workout or who just wants a sturdy multi-functional timer.

I'll give it five stars because it does exactly what I need and it's great value for what it is, but tbh I found it a bit of a mystery to program and I'm glad I never have to change it now that's set.
I only use it for one thing, which it's perfect for. That is, a continuous cycle of 40 seconds for a stretch – alert- 5 second interval to change position – alert.
The vibration alert is great: it means you don't have your podcast/music interrupted by any noise , or struggle to hear it over your headphones.
I feel they could have added a button and an indicator on the display to make it easier to program. But, maybe I'm just getting old and dumb.
