Gymboss miniMAX Interval Timer and Stopwatch - Black/Yellow SOFTCOAT

I love this interval timer, but it was an absolute chore to figure out how to change a saved program once I had entered it and then later changed my mind and wanted to update it and save again. I asked the question here on Amazon and no one responded, so I'm assuming nobody else has needed to do this (or has figured it out). The instructions indicate you should just go into your saved program, change it to however you want it, and then save it. But it's not that simple, and I exchanged at least a dozen emails or more with the company before realizing how I needed to change it. They were responsive about answering my question in a timely way, but their responses didn't clear up the confusion. So after a bunch of emailing, I had pretty much given up on being able to change an existing saved program. And there is only room on the device for about 20 different saved programs, so you wouldn't want to have to keep creating new ones as you changed your mind about a workout.So here are the details of what I needed to do and how I did it:Let's say you have saved a workout in the Multi category and it has 7 different intervals. Then you change your mind and want to eliminate interval 4 so you'll only have 6 intervals. You can't go into the saved workout and delete interval 4. There is no delete option on this device. Also, the device won't let you set interval 4 to last zero seconds. I tried that and the minimum number of seconds it will allow is 2 seconds. So I thought the best I could do is have a bogus interval 4 that lasted 2 seconds which I would have to ignore.The critical piece of missing information that nobody mentions is that you have to go into the saved workout and RE-ENTER EACH INTERVAL FROM THE BEGINNING TO THE END. If you re-enter each interval, you can make intervals 1, 2, and 3 the way you want them, then you make interval 4 look like the old interval 5 looked, and you make interval 5 look like the old 6 looked, and the final interval CAN be brought down to zero seconds. And then you can save it that way and you have essentially deleted interval 4. When you re-save a workout, it overlays the previous version of that workout, so you won't be wasting one of your 20 on a useless workout.I guess I could have rated this unit less than 5 stars because of the terrible instructions and the less-than-helpful email responses, but the unit itself is really great. So I decided to rate it based on that instead.And as others have said here, be sure to print the official instructions you can get from the gymboss website rather than trying to use the terrible instructions that will ship with the unit. Armed with the official instructions and the information I listed above, you should be able to figure out how to enter and update some great workout interval programs.

I ended up using this for 4-7-8 breathing exercises. The multi function is perfect for this. The tones and vibrations are super loud and very tunable for your needs. I'm very happy with the timer.

First off, a few responses and additions to what I saw in other reviews:1 - The included manual is well written but incomplete. Several functions are not mentioned. However, that said, after using the directions to set up my first program, I found the controls to be reasonably intuitive with the following exceptions: a) stopping the timer, b) the logic behind the "P" repeat setting is unclear, and c) the alarm setting indicator on the display (lower case b is a soft beep, capital B is a loud beep).2 - The build quality is solid enough, but could easily be made watertight. The top buttons are also not quite seated properly - slightly misaligned. The function perfectly, though, so this is not an issue. Also, the LCD display will distort a bit when I just rub my finger across the screen - also, not really an issue, but a bit concerning.3 - Your programs DO stay loaded when you change the battery. If you want to clear them, there is a recessed "reset" button on the edge opposite the "start" button.Now, for the overall pros:1 - The customization is adequate to use for almost any imaginable interval training you want to do. Using the "multi" mode, you can program up to 25 distinct intervals, with each repeating any given number of times up to 99, and you can have your entire sequence repeat up to 99 times. It's hard for me to imagine a workout that can't be programmed into this thing.2 - It is light weight and compact. Wearing it on an armband while running, you hardly notice it.3 - The vibration alarm is just strong enough to be easily noticed without being annoying.4 - The color scheme looks pretty good.As to the cons:1 - The GUI is hopelessly out of date - like 1980's out-of-date. It wouldn't be that hard to include a micro USB slot and program an app that would let you program this much more easily - and probably provide even more flexibility in the programs. That would also free up display space.2 - Only a few color schemes to choose from. This fix is easy, cheap, and will make it more appealing to more users right away.Overall, if you're looking for a simple device that gives you plenty of flexibility to create the workout you want, this is a great device. I highly recommend it.
