Summary: I bought this product 2 and a half years ago. To start with, all went well. But within a year it was starting to cut out intermittently - the first time was when I was running my first half marathon so I was really annoyed.
Summary: the unit worked fine until the battery stopped accepting a charge that would hold for more than about 25 minutes. Garmin was not sympathetic as i had the unit for less than 2 years, but for more than one year, which is over warranty. a rechargeable battery ought to last more than 2 years.
Summary: I tried everything to get the heart rate monitor to work ...but it would work maybe 1% of the time... so I would rate the monitor junk....the rest of the 305 is okay but it is the heart monitor I really wanted.
Summary: Have owned one of these for 4 weeks now and have yet to successfully record my heart rate for a complete run. Drops out on every occasion. I have tried everything recommended by Garmin to get it working without success.
Summary: This watch was great while it worked but . . . the heart rate monitor stopped working in less than six months. Garmin then gave me the run-around. After I bought my own replacement strap -- $50, didn't help -- the finally agreed to replace the watch, but they insisted that they be allowed to charge...
