Not 100% related to the Descent Mk2i but partially so I am posting it here.
I just got the band 2 days ago so these are initial impressions, first overall impression I am very happy with the band.
- The great it makes the watch look dressy enough that I can easily wear it with a suit in a formal setting and not raise eyebrows (not that I really care about other peoples thoughts but apparently my employers do).
- The dual tone charcoal looks great and adds a nice touch
- The band is very comfortable and secure
- The band is adjustable both via removing links and micro adjustments on the clasp, however if you have small wrists you need to be aware that you really only have 2 or 3 small links per side you can remove. I first took of the largest links and only after did I realize (I should have seen it but was so excited I did not look carefully) that due to the tapering you really cant remove the top 4 and I am not even sure you can remove the 5th link meaning you only have 2 (maybe 3 removable links)
- Now for the annoying the interior of the band is highly polished so it slides easily
- I wish the band had a spring loaded clasp like my Breitling (and before you comment, the vented titanium band is $300 US (420 Canadian) so it's not a budget item
- I also wish there was a wet suit extender on the clasp (sure I can use the rubber strap and I likely will but it's titanium so it can handle the salt water)
That being said overall I am very happy with it. I have done a couple runs and it is comfortable and while the HR is hit and miss as it moves I honestly dont care for 85% of my runs when I do I can swap strap (takes 30 secs or less) I have done several cardio workouts and because it moves it is inaccurate on counting reps but again who cares as the workouts are just for fun and I am not that fussed about the actual stats.
It's a heavy combination, so honestly I dont see using it on any run over 10K but time will tell (first couple runs of the season and I am not doing any more marathons so we shall see on half marathons, but I have my forerunner for that).
