I really like that it is a smaller watch/altimeter for those of us that have smaller wrists. Or are just female and dont want to put on a man's big bulky watch. But by bringing in the sides, aka, making the viewing area extra small. It was too hard to navigate and read. I do believe they could of kept the same size and just not take up so much room around the circle so as to increase the viewing area.

I bought this watch primarily for backpacking in the mountains, and it worked GREAT. The reported altitude was usually pretty close - VERY close considering it's a barometer-based altimeter. Unfortunately though this watch went to the Great Altimeter Watch Place In The Sky when it went kayaking in the Bahamas with me in November - although it's supposed to be waterproof to 50m, it fogged up, filled with water and ultimately died about halfway into the trip even though it was never submerged more than a few inches while paddling. I was totally bummed, but I may try another one because I'm a woman and I don't have big manly wrists, and as far as I know it's the only altimeter watch out there that isn't so big it has its own zip code.

I got this altimeter watch so I could keep track of my total ascents for a hikes or bike rides. I like that Highgear made the Axio Mini actually pretty mini. It is a good size for my small wrist. I did need to reference the manual, but after a bit of review, use of the watch seems pretty straight forward.
