Unfortunately I didn't have enough time to try everything out and test to see if it had fixed it (which would have involved going for a 4-5 hour run) before my marathon

Features worked half the time, and now the vibration feature doesn't work anymore, and the features are a miss

I love the looks of this watch and when it is working it is great, unfortunately it is very unreliable at the most important times.

For example, I forgot to click my Start/Stop button at the right times during my triathlon (my fault) so the time was messed up

If Casio can charge their watches from sunlight or other light sources why not Garmin?I do not need anything fancy in the watch like seeing my incoming calls or text messages ( that is an Apple thing :) ), I need longer battery life with GPS and HR monitor on, I need accurate distance keeping, altitude keeping and accurate time keeping over the distances I run.

+ just a couple of months ago) to have a different model sent and not waste any more vital time during my marathon training

I have had this watch for maybe 6 months now, it crashes all the time

I'm warning all of you, do not waste time or money with Garmin products.

I go on my activities, but in the end, I still have to carry my iphone with me since this watch limits the functionality of the software, and lets face it, the iphone never crashes and works how I expect, every time.

They promise a three day turnaround time, and I got my response 8 days later from someone who obviously did not read my message

I got a "Track Archive Error" the third time I tried to log a hike

I have crashed so hard and banged the hell out of this thing on rocks several times, causing scratches,

Issues encountered include:- Unit shutting off at odd times (like pressing the stop button to stop an activity).- Unit freezing up completely in the middle of a hike, then correcting itself an hour

Every time fails and the watch turns off

I has some troubles setting the right time in Venezuela but isn't Garmin foul

I AM WASTING MY TIME , because I already lost my money , but I hope help someone to avoid this model

, I had the 305 and 310xt and never had a problem with them, since the august with the software update any single time that i used it the watch it reboot itself, doesn't sincronize anymore, I had enough patience and try everything that I've found in google, youtube, garmin.com, and is simple, Doesn't work

For example, I forgot to click my Start/Stop button at the right times during my triathlon (my fault) so the time was messed up

Still trying to figure out what is going on, but sometimes the time is completely incorrect.- Occasionally locks up when trying to view history.- Doesn’t support separate heart rate zones for running vs. biking (910XT does).- Won’t sync heart rate zones with Garmin

GPS track is really off route, hard time to calibrate compass and make it work properly.

Features worked half the time, and now the vibration feature doesn't work anymore, and the features are a miss

As I don't have the HRM Premium strap, I miss the vertical oscillation and the ground contact time, but the cadence works fine and it is useful for improving running tecnique

and it froze up on me several times

Based on reviews I should have never wasted my time with this watch but decided against my better judgement.

It is much slower ( several times less throughput in terms of processing ) as compared to Forerunner 610XT

This is my third different model of garmin gps watches, and it is by far the worst and most probable the last time I buy a Garmin Watch

It does exactly what a GPS watch is supposed to do (and more)The Cons:-Finding satellites take a long time

The display does not "refresh" with the correct time

Perhaps 4th time's a charm?

Two years of use, maybe a few dozen + times, dead in the water - from disuse?

In fact that is the only time it's easy to read

had other Garmin Forerunner watches, and they are much better than this.- Reports incorrect elapsed time.

The info and analytics are great and very useful to keep improving my resistance and times

I get compliments on it all the time but takes forever to link up to satellites

Despite returning the unit for a warranty replacement multiple times the unit continues to suffer from a "low memory error" which can cause the unit to crash and become unresponsive.

n’t work
