Bought this for mostly for walking, it's still early days but so far I cannot fault it.

It is very well built and bigger than it looks in the pictures, overall 5 3/4" x 3" x 1 1/2", it has a 4" screen, that is overall 3 1/2" x 2", much bigger than the Satmap gps screen, it is the biggest pocket sized gps I could find, which is exactly what I wanted, I find with most gps the screen resolution and detail of maps is great, but to navigate easily you need to see what is around you to get some perspective, by the time you have zoomed out on a smaller screen it all becomes hard to see, the bigger Montana screen really comes into its own here.

I am really pleased with the sensitivity of the receiver! I can switch it on anywhere, indoors or out, and it knows where it is in seconds, compared to my Satmap unit which often takes 3-4 minutes to decide where it is and has to be outside or at least by the window, or worse still my (much) older Garmin unit which has to be waved around in the air outside!

I went for a walk with the Garmin switched on, but left in my coat pocket, I got it out and checked it every 10 minutes or so and was amazed to find it had not lost itself at all, considerably better performance than the Satmap unit it has replaced.

The Montana comes with a respectable and quite useful base map, but as always its the detailed maps where they get you, mine will potentially get used all over the UK, the entire country 1:50000 OS map micro SD card cost me an extra £200-00p.

It can show 3D maps and the screen automatically switches between landscape and portrait depending on how you are holding it, I have bought a suction pad holder to use it as an in car sat nav if I need to.

I had a primary list of specific needs, which included:

* OS 1:25k walking in the Cotswolds, but with some occasional walking elsewhere.
* Reliable, robust, waterproof
* Long battery life and off the shelf (AAA) backup, to eliminate any battery life anxiety
* Some compatibility with my heavy investment in Memory Map (MM) maps over the years
* Integrated road navigation so I could easily find the start of walks

Wow, it does all of the above and much more, and SO elegantly. Love the screen size, and although it's quite thick in depth, you don't notice it as it fits neatly into your hand (ie within the crux of your hand - a wafer thin unit wouldn't be any more convenient, just lighter!)

Added to the above, it does a whole heap of other things which I hadn't expected:

* Size convenient enough that I'm happy to run with it, and with RAM mounts, I now use for long cycle rides and as a motorbike GPS (waterproof and 22 hours of battery life means you may not need the powered mount)
* 3D compass is amazing and integrated. That's to say you can flip from map to compass, and it will show you exactly the direction to head (usually with GPS, if you've stopped without fixing a direction, when you start again you need to move in any direction in order to orientate yourself)
* Tailor your profile, so you can easily switch between Auto mode (e.g. landscape, turn by turn instructions to find your route start) and Recreational (e.g. portrait, lock screen orientation)
* The camera I thought was an unnecessary feature but I've found it fabulous, and takes great pictures.

Bought to replace a SatMap which malfunctioned (broken toggle switch). This is a big unit: 144mmx78mmx38mm and weighs in at 300g with Liion battery loaded. Screen is 102mm diagnonal (4 inches). Bought primarily for hiking with 1:50K OS maps. This review is written 2 years after delivery. I've used this a lot with no issues. Liion battery lasts around 12 hours and can be swapped easily (unlike Satmap) for 3AA's. Lots of built in functions, including compass. Never had any problems with GPS lock (including in-vehicle usage). Note that this is useless for road navigation. It's route planning abilities are pathetic. Driver guidance is absent. Buy a TomTom. You can upload trip details onto a PC (.gpx files). It also has trip meters, times, distances etc. Don't rely on its altitude gain estimates since it uses a built in barometer and on a gusty day it over-estimates climbs by a lot. My only gripes are:
1. Map rendering is slow. This is not an issue for navigation since it easily keeps up with walking pace. It is irritating if you want to browse a route.
2. You can't lock-out the touchscreen. This means that if you leave it in a rucksak with something rubbing on the screen it will burn thru the battery faster than you want. This is irritating, hence the loss of a *.

We've had a while to check this GPSR out and it has been a definite improvement over our previous Garmin - larger screen, seems to be better at acquiring and keeping satellites, camera and a huge memory so we don't have to keep deleting pocket queries just because of space. On the downside, it has a tendency to sometimes freeze for a moment - usually when re-loading a map, and has 'bricked' on a few occasions where nothing happens at all and it has to be turned off and back on. The freezing is no worse than the previous Garmin but the 'bricking' is a pain. Would I return to the old GPSR? No, I wouldn't. The larger screen, bigger memory and camera more than make up for the occasional glitch. The buying process was very smooth.
