Summary: I have a Garmin Vista Hcx that I bought this to replace. It was a mistake. The battery life is crap, I mean really crap. Make sure to pack a spare pair or two. The screen is hard to read unless you crank up the brightness which you can't do with a low battery and it always has a low battery. It seems to measure everything a bit long. It is water proof, I've check on more than one occasion, I take it kayaking with me.
With 100K topo only this unit will not set a direction to a waypoint.

Summary: I've used Garmin for quite a long time. I bought the 450T for a hiking trip to Isle Royale in Michigan. If you haven't been you are missing a great place to hike. In eight days we hiked about 55 miles on this beautiful island National Park. After getting back last night I've decided to return the 450T. Although Garmin does tell you upfront the 100K topo map is not routable. Meaning it will not follow the trails so clearly marked on the topo.
Summary: I bought this for my wife who intended to use it for finding geocaches - a very interesting and fun hobby by the way. The device is awesome but limited in an urban setting without enhancements. Unfortunately, this device only comes with basic "earth" maps and no detailed street maps. Since we live in a populated area, we thought it would be useful to see the streets. What I discovered when I called Garmin shocked me. The maps that come with the unit are very basic.
Summary: I bought this unit from Amazon after having owned a LOT of Garmin products over the years. It was a mistake. 1) The high resolution display is extremely difficult to read in sunlight. Since I didn't buy it to use indoors, that's a real problem. If you hold it at just the right angle to the sun it looks good, but if you have it on a bicycle mount it is almost never at that angle, which means you can almost never read it. 2) Battery consumption is terrible.
Summary: The Oregon 450, as well as the 550, has important software problems: The trip odometer readings are about 15% less than the real distance. The stopped time shows absolutely wrong values, sometimes the stoping time is longer than the total trip time! It seems incredible that Garmin delivers such expensive products with bugs like these, while older units as the GPSMAP60CS(X) performed well. Most e-mails about the problem are not answered.
Summary: I've had difficulty performing the simplist of tasks with this unit: Examples: 1) using the Trip Computer to record the time and distance of a walk - it adds 4,5,20, whatever it feels like, kilometers to the distance walked. The selected registers change to others not selected (vertical speed??). I continually reset it to try and get it to act like a simple trip meter. There may be an explanation but I did not want to think that hard about this tool.
Summary: I purchased this unit last Feb and was very happy to get. The touch screen was a nice addition to my previous units. I added additional 3rd party maps which worked well, but ran into several cases where i had to disable additional maps for the routing to work due to the limitations of the waypoints/routing. Used it once for Geocaching.
Summary: I'm sure the hardware is excellent, but unless you are a GPS geek it's very difficult to use. Supplied documentation is poor and many of the menus are far from intuitive. Likewise the BaseCamp software that you can download from Garmin to set up routes on your computer is badly designed and poorly documented. You shouldn't have to spend hours poring through user forums to work out how to get started.
