Summary: I could write a book on this thing. And I think many have. For me it worked great at tracking my ride through Central America. However it was absolutely terrible at direction finding. These devices just are not any match for a smart phone and google maps. One advantage was the battery life.
Does some things well, but many advertised features simply do not work.

Summary: For general GPS tracking, stats, uploading your rides to your favorite fitness site, etc - this is a great GPS. The display looks great and with an SD Card getting maps on to it is easy. That said, it falls on it's face after that.
the maps function really isn't as good as maps on several free biking apps i have ...

Summary: Several things force me to rate this only average. First, it didn't come with maps, so I immediately had a 79 dollar charge to purchase maps. Then, the edge doesn't come with enough memory to download maps, so you have to purchase a micro SD card.
Okay, after investing another $115 in map pack and memory card

Summary: I loved my Garmin Edge 800, and this is easier to create bike and training profiles, and allows you to quickly change between road riding and trail riding navigation. But my big problem is that it doesn't come with any useable maps installed.
Summary: I've had the 810 for about 3 months and about 1,000 miles worth of (road) riding and can finally put a review on it. Plain and simple: If you want this for the new "bluetooth" features, forget about it.
Summary: Well constructed, but battery life has not matched manufacturer's claims (12 hrs vs 17 claimed) and that will only degrade over time as will all L-ION devices but since this is a sealed device that becomes a bigger issue.
Summary: The Garmin Edge 810 is nice. I was torn between three stars and four. The device itself is very nice. Battery life, with GPS running, is solid. The screen quality is pretty decent, but it's not a sharp high-res screen that you're probably used to from things like your cell phone or tablet.
Summary: Great unit and tells me everything I need to know, however Bluetooth stopped working within weeks and the cadence sensor stopped even sooner. The HRM is good but having spoken to many Garmin 810 owners the issues I have had are standard, I decided to keep the unit rather than box it up and...
Cons: Expensive, Low Quality, Limited Color Choices
Summary: I bought the 810 to replace a nearly 5 year old 705. Back in '09, the 705 was a revelation for me. Being able to navigate and load detailed training plans was fantastic. Being able to discover new routes in unfamiliar areas opened my eyes.
