the bezel be very frustrating . it either scroll for you or it do not and there be no reason why . sometimes when my finger be just near the edge it would change screen . I would have to push hard and the next time a feather light touch change the screen . the gp and hr monitor work great and the hr strap be comfortable . the amount of stuff it can do be amazing but I think you need to be a professional athlete to use it all . the Garmin training website be not very good and there be no direction on how to use it . I use it with mapmyrun.com and it download seamlessly . it also download fast with the Garmin training site but every time I want to stop it give I some Garmin error . I be a female and the watch be really uncomfortable and large . female , I do not recommend it at all . it rub on my wrist bone the entire run . I would try to readjust it and the stupid bezel would get touch and change screen . I think it would fit a man 's wrist quite well though . the battery charge go very fast . I do not get it past 65 % because I keep plug it in . go from screen to screen be a pain with so many feature . for a serious male athlete I would recommend it . pro : great for serious athlete compact and clean look for a man 's wrist lot of feature , interval , simple , advanced , hr zone 1-5 and 3 training plan hr strap comfortable and I never have a issue with a inaccurate rate sit , run or sweating backlight be very bright -lrb- although it would come on if my finger get too close to the bezel -rrb- con : Way too clunky for female wrist bezel be finicky at best , hard to control . impossible while run too many feature for a newer runner . just run my first 1\/2 marathon and even with all my training I do not want or need all those feature . the price be way too high when there be other watch that can do very similar function just as well .
