Best fitness watch I've ever owned. Only fitness watch I've ever owned.
I bought this watch for the gps feature, to help track distances and routes for free ride mountain biking but have found that I use it for much more than that. The ugliness of this watch will grow on you when you find out how much it can do. It links to your phone so it alerts you to phone calls, texts, emails etc. And living in a state that has a hands free law, it's kinda nice not having to look for cops every time you get a text. That's a joke actually. I don't text and drive.The gps is super accurate when you select "high accuracy". It will even show you what side of the street you're on when you go to aerial map on the app.The sleep tracker is really nice not to mention accurate. Working midnights, I struggle to get adequate sleep. With my Polar, I can always track my patterns.The heart rate monitor is accurate but sometimes it reads it a little slow. Would be nice if it was a tad faster.The battery life is ok depending on what you do with it. I use the gps on high accuracy every time so I have to charge it every few days. On the other hand, I've been backpacking with it and used the gps on power saver mode and it lasted the full 5 day trip. Then it still had enough juice to last two more days under normal wear before I charged it.The backlight is very good. It's got a low level backlight that turns on with every button you push. Which you won't even notice in daylight but will when in low/No light settings.The upper left button will engage the high output backlight. I have never found a need to use that one. The low level light is plenty.I put a case and screen protector on it to keep it safe during hard mtb rides. The watch seems to be a winner, other that it's appearance. I think it's kinda ugly. I'm use to tactical style watch, this has more like a yuppy smart watch look to it.I've yet to wear it swimming but have worn it in the shower. It has a swimming program on it so I'm assuming it can handle it.This watch does have an alarm but uses a vibration alert instead of one you can hear. This is soo much better. I've yet to sleep through it. In fact, if you're asleep and the alarm goes off, it scares the crap out of you. I'll never go back to a regular watch alarm.The only thing I wish it had was a regular timer. It's got a distance timer but that doesn't really help me when I'm cooking a frozen pizza. But oh well. Can't have everything, I guess.Seems to be plenty durable as well.
