Summary: The GPS doesnt perform propely. I have been out for running 5 times and in 2 of them the GPS signal is lost. I dont what the problem is, but my last watch, Garmin Forerunner 405, lost GPS signal very seldom.
Summary: I disconfirm the water resistance properties: after one year of normal use (not more than 6 meters submersion in the sea) this watch leaked, the screen sweated; in addition to that there have been 2 serious hangups that I was unable to handle. On the first occasion I had waited for the battery to die, and when charging the watch restarted and worked; on the second occasion, sometime after the screen sweated, the watch never restarted.
Summary: I had this watch for the better part of a year, seeing it go from software v2.60 to v4.00. This was an ambitious project, stuffing a full-fledged GPS into a watch, and so I patiently waited for Garmin to iron out the bugs and make it more stable. And I waited, and waited, and submitted bug report after bug report.
Pros: Comfortable, Compact Design, Easy to read, Modifiable Menus
Cons: Slow to acquire satellite, Slow To Respond, Unreliable
Summary: First watch I purchased from Amazon, about a week after wearing it condensation formed inside glass of watch. I've read this is a problem in the manufacturing. I returned it and received another watch. Second watch I received from Amazon, about a week after, I was wearing over my wetsuit doing a 40-50 foot freedive in the ocean (watch is rated to 50 meters/150 feet) and on my ascent the watch started vibrating on my wrist (it's not supposed to vibrate).
Summary: I have been using GPS devices for years, mostly for running, trail running, hiking in the Sierra Nevada, and biking. I chose the Garmin Fenix in March of 2013 because it offered a long battery life, and I was training for my first ultramarathon. I also liked that the device had an altimeter, even though it didn't have some of the features that the other Garmin running GPS devices offered. I just like to strap the watch on, go run, and load it to a website later.
Garmin Fenix NOT WATERPROOF to 4.5 inches (never mind 50m)
Nom De Plume, Amazon
26 March 2013
Summary: I'm a long time Garmin owner I must have had at least 15 products from them over the years. Most are excellent well designed and engineered and I've kept them until they died of old age. But the fenix - I got this one Feb 18th 2013 and worn it every day for nearly 2 weeks - and everything was great until, I submerged it in a glass of water - 4.5 inches to be precise - for half an hour. The garmin website state waterproof to 50 meters - that's 164 feet.
Summary: While all the features are there and the watch works beautifully when it works, it lasted for two hikes and one surf session before coming up with enough condensation inside of the face to make the data virtually unreadable. I tried to dry the watch out in the sun and with a desiccant but to no avail. A few hikes later and the watch would shut down spontaneously and/or not turn on unless connected to a power source.
Summary: Unfortunately, it turned out after swimming in the pool that this pricey watch is NOT waterproof, and I did NOT press any knobs on the watch. So you announce a 50-meter depth waterproofness for this product and it is simply NOT true. Very disappointing for such a pricey watch. I have read on the net that Garmin is now offering a new waterproofed Garmin Fenix. So it seems that it is time for a product recall. Folks do not get cheated.
Summary: Great watch but the altimeter function on the one I received was very inaccurate. Ran a 3000 foot ascent on a hike that 2 other Garmin units (Montana and 60csx) read as about 800 feet. Constantly showing altitude where I live correctly as about 1000 feet then 30 minutes later showing 2500 feet even though I was in the same location. GPS function and other functions were good and it can be customized in many ways.
