I want to do a 5-minute warm up walk followed by 7 one-minute runs with 2 minute walks and a 5-minute cool down. Will it do that?

You could walk for 5 minutes and then turn on your gym boss set for two intervals= one minute and two minutes.....do your run / walk intervals then turn it off and walk your five minute cool down

Does anyone know how this model compares with the older model? Did they improve the quality/usability, or is it just aesthetically different?

After using old and new version here is my conclusion:The old version was good; loud, strong vibrations, easy to use and small. But it had its issues the battery cover would frequently fall off and the belt clip would break off too easily when it was in your gym bag or if you knocked it while exercising.Thankfully the new version seems to have addressed these problems. They have made it so the belt clip is removable so it won't break in your gym bag and having looked at the clip itself it seems more solid so it seems like this will be much more hard wearing. Been using the new model for about 2 months 6 days a week and no issues. Hope that helps

How long does the battery life last - will it go longer than 5 hours in one run?

Yes, the battery will last longer than 5 hours for one run. I used the Gymboss for my long runs on the weekend and completed a marathon and quite honestly I don't remember the last time I had to change the battery!

Can you set it so it only vibrates but does not make a sound?

Yes; when going through the set-up phase,get to the point where the "Bv" or "bv" (beep-vibrate) is flashing. Then simply push the top-left button until only the "v" shows.
