Pros: Great features and battery life

Cons: Rubber USB cover breaks easily, connector is still waterproof, I just used an electronics putty to keep the dust out.

Recommendation: You can grab one used for $50-$100, and they're easy to find. Get it!

Pros: Great as bike computer and GPS, easy to use, robust, waterproof, great display!

Cons: The price and the annoying flap that covers the USB port (and falls off all the time).

Recommendation: Have this since 2009. I don't use the training center software at all, just the Garmin connect site. I use MapSource for adding tracks and POIs, and a routable version of OpenStreetMap. Really easy, I just pick a map for my area of interest and upload it onto the MicroSD (2GB). If you keep the map small, even the routing works! Survived a couple of crashes, only damage is a slight scratch at the side of the display, which doesn't interfere at all!

Model/Year: 705 Edge; 2010

Pros: Great idea. Navigation would be nice if it worked. Database of places is a cool idea. It does tell the time, cadence, heart rate etc. when it is working.

Cons: Very unreliable. Locks up often. Looses data. I am on my 3rd warranty unit. Sometimes only the grade % and elevation does not work. Its very odd.

Recommendation: Don't waste your money. Don't get an 800 either - they haven't gotten the bugs worked out of the 705 yet!

Pros: Amount of features, waterproof, light, mounting.

Cons: for the price the unit needs to come with unlimited maps and updates.

Recommendation: I love the unit so far, even though it's high priced it will pay for itself.

Pros: Fairly easy to use, very accurate, light and sturdy. Garmin Connect site is well done.

Cons: Wish I could edit my maps before uploading them to the Garmin site, especially when I accidentally log two different rides together.

Recommendation: Definitely worth it, but buy one on eBay where it will be cheaper.

Pros: Color screen is beautiful, even in sunny conditions. Navigation features rock and the interface is improved over earlier Edge models.

Cons: Expensive. Still not completely intuitive process for transferring and loading maps. Internal memory is a bit limited.

Recommendation: A powerful GPS is a rugged, cycling specific form factor. This is the mac-daddy of mountain bike GPS units but for most casual riders it could be overkill.

Pros: Size, Mounting location, ease of use, water resistant

Cons: Expensive

Recommendation: I would probably purchase this unit again.

Pros: Easy to use and set up

Cons: Not cheap and then you need the maps

Recommendation: Having used a bike computer and a GPS with no mapping for 2 years I upgraded to combine in the 705 and go the local 1:50,000 maps. So much easier to find new routes to ride. Expensive but if you can buy it you should. You won't be disappointed. Don't get the cadence unit for MTB.
