Feature wise this watch is great.

The construction is pretty bad though. I have a fairly thin wrist for a guy, and it was never really comfortable, but despite all it's bulk two of the buttons broke and the watch became unusable within about 3-4 months of use.

This is not abuse, mind you. I was hiking and would use the buttons normally, and their plastic just cracked down the middle. I don't think I ever hit it against a rock or anything.

In short, be gentle and the watch will work well if it fits you.

I bought this watch for my husband for Christmas. The watch literally has not been off his wrist. He is a ski patroller, fitness junkie and he uses the watch for all sorts of stuff!!
It has not let him down yet!
He had been looking for similar watches but this one has everything he wanted and was surprised when he opened it up Christmas day.

I liked the watch software, it has everything I needed but the size and the design of the watch make it very painful to use. I had to return the watch as it was rubbing against my wrist bone and becoming impossible to wear as it was turning into a bad experience.

If memory serves, someone on these pages referred to the AXN 300 as a "big honking watch". There is no getting around this. But if you can live with that -- and I can -- it's a solid performer and lives up to what it promises.

I bought the AXN300 as I wanted a Heart Rate Mon and Altimeter in one to avoid having two watches and also for skiing, backpacking and the likes. The options were few and far between. I ended up returning the AXN as it was too large for me to wear on a daily basis, whatever about hiking a 14er. I chose the yellow one for the less masculine option, but boy does it glow. You need one big wrist for this baby.
