Good and bad. The speed in which this unit connects to speed, cadence and heart rate sensors is amazing compared to what I have used in the past to include other Garmin units. It connected to my phone via Bluetooth easily. The speed it connects to the satellites is pretty amazing as well. All in all, a fairly easy to use unit though I have not figured out if you can modified the data display screen yet in terms of adding or removing boxes of data which is annoying. Its not completely intuitive in my opinion.
The bad, the price and what you get. This is $500 which is as expensive as most high end phones you might buy without a contract. This unit isnt nearly as complicated or stuffed with as many features as a phone but, I will not ride with my phone mounted on my bike and my phone currently doesnt connect to the sensors. The screen is usable but there is a learning curve with it. Dont expect it to act like your phones screen. Also, while the screen does what it needs to, at this price I think it should be higher definition. Now for the REALLY bad, you wont get anywhere close to 13 hours out of the battery. Using it as you would in most outside situations, meaning Bluetooth on, screen at maximum brightness etc... youll get about 5 hours if you are lucky. Its probably fine for what most people will do but its the idea that Garmin would KNOWINGLY mislead people about this units battery life that annoys me. I want one GPS unit for all outside activities I do. Is it too much to ask to get a unit like this to work for hiking and golf for no additional cost? No its really not. Not when phones can do the same these days for less money. Also, 40 bucks for a piece of plastic to mount this unit the way it NEEDS to be mounted to make it the most useful it can be? Seriously Garmin, you are going to nickel and dime people like this? I wont be sorry to see you go when phones finally do everything.
