I guess I'll be the lone naysayer. I use a 620 and have had a 910 and 405. Each one had major bugs that make me shocked that they shipped. It seems that the general feeling from my friends who use their products, is that Garmin does a less awful job than Polar at providing fitness tracking for athletes. Just one example, it's a common and known issue that putting the 620 on the charger will sometimes drain it completely. There's magnets that hold it in place so there is no chance the proper connection wasn't made to produce a charge. Even if there wasn't any charge, it shouldn't drain it, but numerous times when I've gone to grab my watch off the charger, I've found it dead. For perspective this is a $500 top of the line watch that they offer.
