Brandon Rizawrote a review of TomTom Spark Music Plus Cardio GPS Watch on February 14, 2016
311 has grass roots, cmon!
(Obscure jamz reference...)
I took the Spark Music Plus Cardio GPS out on a trail run through Marin Headlanads in the Bay Area today. I'm loving the simplicity of this thing. It's really a "fire-and-forget" type of device, and while I won't use it in the same way that I use my Suunto Ambit 3 Peak (loading in tracks I drew on GoogleEarth, following those tracks in the mountains, comparing lat/longs from topos, tracking my ascent rates, etc...) I WILL use it extensively for training loops around town . The speed with which it grabs satellites is impressive when those satellite's positions are updated with the phone app everytime you sync it. I love the fact that I can load in tunes, but I still haven't figured out a way to CONTROL the tunes once I'm in an activity profile. (I can't seem to change songs, repeat songs, etc...)
I know it's not too fair to compare battery times to the Suunto Ambit 3, which, as I've testified to in other reviews, is just downright incredible enough to actually be useful for 36 hour pushes in the mountains, but the battery in the Spark Music Plus Cardio GPS leaves a little to be desired. It's not as bad as what I've read online that some people are complaining about...I guess people just like to complain. In my experience, once I charge it, it'll track my daily activities for about a week if i'm not grabbing satellites. When I'm using it to run daily I need to recharge it every three days or so, but i'm using the MP3 player the whole time I'm running. I find the battery life to be totally acceptable for what this watch is doing.
More later as I keep using it.
