my wife buy I the Garmin Forerunner 301 for Christmas . I have want only a heart rate monitor , but this gp device be a pleasant surprise ! it work wonderful . it be simple in design and in ease of use . it appear slightly bulky , but when I wear it on my run , it do not bother I . in fact the large screen be easy to read . I mainly do 5k run , so it be not like I be wear it for a extended period of time either . but all in all , for what I use it for , it exceed my expectation !
